Winter 2016/17 - Pioneering in a brand-new study program, exploring opportunities and co-shaping the program by feedback and student initiatives, studying in a program which is evolving semester-wise: MSNE Alumni/Alumna Steffen Schneider, Christoph Kocher, and Ann Kotkat are going to look back ~4.5 years, discussing their impressions on ENB MSNE Program, their time at TUM, their time in Elite Network of Bavaria, putting a focus on their year(s) after graduation. The discussion is intended to provide a student perspective on career opportunities, on time and efforts spent in the program or afterwards that turned out fruitful or a waste of time. The event is open for all MSNE students, all MSNE alumni/alumnae, and MSNE associated Faculty/Team. We would like to keep this audience fixed to this group of people.
Preparing for the event, we asked three open questions to Christoph, Steffen, and Ann:
- Being in a time capsule, given all the knowledge you have now, re-starting to MSNE: What would you do in a different way?
- What have been your thoughts while deciding between PhD / Doctoral Studies at University and (research-.oriented) Industry Employment?
- Kindly provide a preview on your calendar entry of Friday, Jan 19th 2024, given that all the plans you made for the next years will turn out successful!
We will meet for this Panel discussion Tuesday, Jan 19th 2021, 18:00 in Zoom. MSNE students, MSNE alumni/ae and MSNE Associated Faculty/Team will receive an personal invitation soon.
Expected end of the evening event is 20:00 (...but we will not close zoom rooms sharp by time).

Title: Investigation of sleep, learning, and memory in the sauropsid brain - Current work and opportunities for student projects
Tuesday, Dec. 15th 2020, 19:00 in Zoom. MSNE students will receive an personal invitation soon.
Current Research Program: My research program aims to study the emergence of sleeping brain dynamics throughout learning and devel-opment. I use non-mammalian animal models, such as birds, to investigate the evolution of sleeping brain states in alternative neuro-architectures. My research uses diverse, interdisciplinary approaches including
• Behavioral paradigms to study natural learning in birds (vocal learning, nest building, food caching)
• Neurophysiology to examine large-scale brain dynamics during learning, memory retrieval, and sleep
• Molecular and genetic tools to perturb neural circuits in real time
• Computational tools to analyze behavior and brain state network dynamics
This work will shed light on the fundamental underpinnings of sleep and memory in all tetrapods by establishing:
• the evolutionary links between sleeping brain states in birds and mammals
• the necessary and sufficient neuro-architectures required for the generation sleep-related brain dynamics
• the emergent patterns of large-scale, synchronous neural activity during development.
Focus of the talk:
After an introduction to my current work, I will introduce opportunities for student projects, such as 6-week and 9-week research projects.
MSNE program manager Florian Rattei will support this event, introducing new students to the concept of MSNE Research Projects and answering student questions.
Expected end of the evening event is 20:00.

Title: Real-time Recognition with Neuromorphic Auditory Systems
Date, Time and Venue:Thursday, December 5th 2019, 17:00 , room N1135
Abstract: A fundamental organizing principle of brain computing enabling its amazing combination of intelligence, quick responsiveness, and low power consumption is its use of sparse spiking activity to drive computation. Recent progress in the development of higher-performance, more usable neuromorphic spike-event-based visual (DVS/ATIS/DAVIS) and auditory (AER-EAR/DAS) sensors along with versatile hardware such as FPGAs have stimulated exploration of real-time sensor processing for wearable and IoT platforms. These sensors enable "always-on" low-latency system-level response time at lower power than conventional sampled sensors. I will describe the circuits of a silicon cochlea auditory sensor that emulates the processing in biological cochleas, the event-driven deep networks that process the sensor data, and the real-time implementation of event-driven delta networks that emulate spiking networks on an FPGA platform with state-of-the-art power efficiency, latency, and throughput. I will demonstrate how we use these delta networks on a continuous spoken-digit speech recognition task.

Title: Eligibility traces and three-factor rules of synaptic plasticity
Abstract: Hebbian plasticity combines two factors: presynaptic activity must occur together with some postsynaptic variable (spikes, voltage deflection, calcium elevation ...). In three-factor learning rules the combination of the two Hebbian factors is not sufficient, but leaves a trace at the synapses (eligibility trace) which decays over a few seconds; only if a third factor (neuromodulator signal) is present, either simultaneously or within a short a delay, the actual change of the synapse via long-term plasticity is triggered. After a review of classic theories and recent evidence of plasticity traces from plasticity experiments in rodents, I will discuss two studies from my own lab: the first one is a modeling study of reward-based learning with spiking neurons using an actor-critic architecture; the second one is a joint theory-experimental study showing evidence for eligibility traces in human behavior and pupillometry. Extensions from reward-based learning to surprise-based learning will be indicated.

Title: Mobile Brain/Body Imaging (MoBI) to image brains in action
Monday, Nov 18th 2019, 17:30 at TUM, Theresienstrasse 90, in semianr room N1135
Abstract: Recent years have shown a remarkable shift in using established EEG technologies to leave the traditional lab environments and to record brain dynamics in actively behaving participants in complex technical setups and the real world. Imaging human brain dynamics usually requires stationary setups and immobile participants to avoid movement-related artifacts from distorting the signal of interest. Interaction with technical systems, however, often requires physical movement to interact with some form of interface to reach the desired system state. This movement itself provides kinesthetic feedback that contributes to and sometimes builds the very basis of the interaction. The brain dynamics underlying such physical interaction are hitherto unknown because of the restrictions of established brain imaging modalities. To overcome these restrictions, new mobile brain imaging methods can be employed. Here, I will give an overview of new technological developments in the field and applications that are now possible using mobile electroencephalography and Mobile Brain/Body Imaging (MoBI). The requirements and pros and cons of different approaches will be discussed and examples for recent interactive VR experiments are shown. In addition, challenges regarding recording hardware and analyses approaches often leading to difficulties in comparing the results with established laboratory EEG-parameters will be discussed.

Title: Neurorehabilitation Robotics: Mechatronic Solutions for People with Movement Disorders
Abstract: Robots for the upper and lower limbs can be very useful to restore movement abilities in two ways. First, they can promote neurorehabilitation as training devices after neurological injuries such as spinal cord injury (SCI), traumatic brain injury and stroke. Second, they can be used as assistive devices to support patients or elders with gait impairments in daily life situations. However, current mechatronic solutions are still too bulky, too heavy, with too little battery power, and thus, too inconvenient to use. Furthermore, the sensory technologies and control strategies are still too primitive to allow the correct motion intention and to provide effective assist-as-needed support. These disadvantages result to unsatisfactory performance and discomfort. In this talk I will present current engineering solutions and future trends of stationary gait and arm training robots as well as wearable exoskeleton devices that can be used for training and assistance in daily life. I will also present the Cybathlon, which is a new kind of championship, where people with physical disabilities compete against each other at tasks of daily life, with the aid of robotic technologies. The next Cybathlon will take place in Zurich, on May 2nd and 3rd 2020.

Title: Auditory-Vestibulomotor Temporal Processing and Crossmodal Plasticity for Musical Rhythm in the Early Blind
Abstract: The auditory dorsal stream (ADS) is a cortical brain network responsible for sensorimotor spatiotemporal processing. However, despite the important role of vestibular input when the head or body is moving through space, as well as the strong coupling between the vestibular and visual systems, very little is known about how vestibular information is integrated with auditory-motor inputs in the ADS, nor is it known to what extent this integration is affected by early visual deprivation. Using functional magnetic resonance imaging and motion capture technology we show that the ADS includes an extension to parietoinsular vestibular cortex (PIVC) and to subcortical regions including basal ganglia and vestibular cerebellum. This circuit is engaged after sensorimotor synchronization training, during beat recognition, and is preserved in the early blind. The strength of activation of PIVC in the early blind correlates with a measure of lifetime physical spatial activity, suggesting that experience with vestibular stimulation via physical spatial activities might compensate for any negative effects of early blindness, and thus reinforcing the beneficial effects of mobility training. Finally, rhythmic entrainment provides an effective tool for studying auditory-vestibulomotor integration and music appreciation, and for developing music-based interventions for early blind individuals.
Biography: Jessica Phillips-Silver, PhD, is a researcher in the Department of Neuroscience at Georgetown University Medical Center and served as adjunct professor in the Faculty of Music, where she developed Georgetown's first course on Music and the Brain. Jessica's research examines how 'feeling the beat' in music is a multisensory experience from infancy through adulthood, and she documented the first case of the musical disorder 'beat deafness'. She currently studies the musical processing and cortical plasticity in blindness with Prof. Josef Rauschecker at Georgetown. She is also interested in the development of musical rhythm and executive functions in Deaf and hearing children, and music and dance as a model of temporal prediction and cooperation in humans.

Title: Nonlinear elastic resonance modes for efficient robot and biological locomotion
Abstract: Controlling motion at low energetic cost, both from mechanical and computational point of view, certainly constitutes one of the major locomotion challenges in biology and robotics. We attempt to demonstrate that robots can be designed and controlled to walk highly efficient by exploiting resonance body effects, increasing the performance compared to rigid body designs. To do so, however, legged robots need to achieve limit cycle motions of the highly coupled, non-linear body dynamics. This led us to the research of the still not very well understood theory of nonlinear system intrinsic modal oscillation control. I will present current theoretical and experimental results therewith. One of the striking results is that biomechanics, in particular kinematics, visco-elastic and inertial properties of biological limbs are such that coordinated resonant motions of multiple joints intrinsically emerges and is therefore easy to excite and sustain. This can be also achieved by careful design for robotic systems. Some of the basic robotics control functions we developed for locomotion strikingly resemble neural functionalities and structures. For example, Hebbian lerning, one of the most basic principles of synaptic plasticity, is mathematically equivalent to robotic controllers which adapt to previously unknown resonance properties of the body. Based on the robot control approach, we propose an equivalent neural model involving neural plasticity in the spine and the serotonergic loop in the brain-stem. This hypothesis is supported by numerous experimental evidences from neuroscience.

Title: Bad performance in sports is contagious: prediction error induced motor contagions in human behaviors
Abstract: Motor contagions refer to implicit effects on one’s actions induced by observed actions. Motor contagions are believed to be induced simply by action observation and cause an observer’s action to become similar to the action observed. However, in our recent work, we discovered a new motor contagion that is induced only when the observation is accompanied by prediction errors -differences between actions one observes and those he/she predicts or expects. In two experiments with professional sportsmen, we show that this contagion is distinct and arguably more dominant than contagions induced by action observation, and can lead to deterioration in performance of professionals after observing a novice. In this talk, I will give a brief summary of my work in “human centric robotics”- in which I utilize parallel research in robotics, motor neuroscience and cognitive neuroscience to improving machines that interact with humans. I will then talk in more detail about our cognitive neuroscience experiments investigating prediction error induced motor contagions, and discuss how this contagion may be the missing link between mechanisms investigated in action observation and action production by humans.

Connecting the structure and function of neural circuits
In this talk, I will describe how we developed deep learning based computational tools to solve two problems in neuroscience: inferring the activity of a neural network from measurements of its structural connectivity, and inferring the connectivity of a network of neurons from measurements and perturbation of neural activity.
1. Can we infer neural connectivity from noisy measurement and perturbation of neural activity? Population neural activity measurement by calcium imaging can be combined with cellular resolution optogenetic activity perturbations to enable the mapping of neural connectivity in vivo. This requires accurate inference of perturbed and unperturbed neural activity from calcium imaging measurements, which are noisy and indirect. We built on recent advances in variational autoencoderes to develop a new fully Bayesian approach to jointly inferring spiking activity and neural connectivity from in vivo all-optical perturbation experiments. Our model produces excellent spike inferences at 20K times real-time, and predicts connectivity for mouse primary visual cortex which is consistent with known measurements.
2. Are measurements of the structural connectivity of a biological neural network sufficient to predict its function? We constructed a simplified model of the first two stages of the fruit fly visual system, the lamina and medulla. The result is a deep hexagonal lattice convolutional neural network which discovered well-known orientation and direction selectivity properties in T4 neurons and their inputs. Our work demonstrates how knowledge of precise neural connectivity, combined with knowledge of the function of the circuit, can enable in silico predictions of the functional properties of individual neurons in a circuit, leading to an understanding of circuit function from structure.

Control of multidimensional systems typically relies on accurately engineered models. Breaking this require-ment is problematic with neural networks, as their Gaussian data assumptions typically do not hold. In my talk, I will demonstrate how this problem can be efficiently solved by combining latent variable models with specific type of optimal control. The theory is demonstrated on various simulated closed-loop control systems as well as on real hardware.

Abstract: Multi-neuronal spike-train data recorded in vivo typically exhibit rich dynamics as well as considerable variability across cells and repetitions of identical experimental conditions (trials). The interpretation of such data often relies on abstract statistical models that allow for principled parameter estimation and model selection; however, the interpretive power of these models is limited by the low extent to which prior biophysical constraints are incorporated. In contrast, mechanistic models are useful to interpret neurocircuit dynamics, but are rarely quantitatively matched to experimental data due to methodological challenges. In my talk I will present analytical, likelihood-based methods to efficiently fit spiking population models to single-trial spike trains. I will first focus on coupled stochastic integrate-and-fire neurons, for which we statistically infer the mean and variance of hidden inputs, neuronal adaptation properties and synaptic connectivity. Then, to infer the low-dimensional collective dynamics I will consider a doubly-stochastic model that accounts for fast independent and slower shared input fluctuations. We reconstruct the shared variations, classify their dynamics, obtain precise spike rate estimates, and quantify how individual neurons contribute to the population activity, all from a single trial. Extensive evaluations based on simulated data, and validations using ground truth recordings in vitro and in vivo demonstrate that our methods efficiently yield accurate results and outperform classical approaches. Altogether, these tools enable a quantitative, mechanistic interpretation of recorded neuronal population activity.

Abstract: In this presentation, I will introduce neuromorphic, event-based approaches for image sensing and processing. State-of-the-art image sensors suffer from severe limitations imposed by their very principle of operation. These sensors acquire the visual information as a series of “snapshots” recorded at discrete point in time, hence time-quantized at a predetermined frame rate, resulting in limited temporal resolution, low dynamic range and a high degree of redundancy in the acquired data. Nature suggests a different approach: Biological vision systems are driven and controlled by events happening within the scene in view, and not – like conventional image sensors – by artificially created timing and control signals that have no relation to the source of the visual information. Translating the frameless paradigm of biological vision to artificial imaging systems implies that control over the acquisition of visual information is no longer imposed externally on an array of pixels but rather the decision making is transferred to each individual pixel, which handles its own information individually. We will introduce the fundamentals underlying such bio-inspired, event-based image sensing and processing approaches, and explore their strengths and weaknesses. I will show that bio-inspired vision systems have the potential to wipe out conventional, frame-based vision acquisition and processing systems and to establish new benchmarks in terms of data compression, dynamic range, temporal resolution and power efficiency in applications such as 3D vision, object tracking, motor control, visual feedback loops, and machine learning in real-time at several hundreds kHz.

At first glance, the monkey brain looks like a smaller version of the human brain. Indeed, the anatomical and functional architecture of the cortical auditory system in monkeys is very similar to that of humans, with dual pathways segregated into a ventral and a dorsal processing stream. Yet, monkeys do not speak. Repeated attempts to pin this inability on one particular cause have failed. A closer look at the necessary components of language, according to Darwin, reveals that all of them got a significant boost during evolution from nonhuman to human primates. The vocal-articulatory system, in particular, has developed into the most sophisticated of all human sensorimotor systems with about a dozen effectors that, in combination with each other, result in an auditory communication system like no other. This sensorimotor network possesses all the ingredients of an internal model system that permits the emergence of sequence processing, as required for phonology and syn-tax in modern languages.

In most mammals, conspecific chemical communication controls complex behaviors. Information about individuality, social and reproductive status is conveyed by an elusive class of chemical cues – pheromones. The highly reproducible character of pheromone responses offers a unique opportunity to uncover the neuronal basis of genetically programmed behavior. Despite its fundamental significance, however, the basic chemosensory mechanisms of social communication remain largely unknown. To address these issues, my laboratory has developed a multi-faceted approach to uncover the mechanisms underlying mammalian pheromone sensing. My research, therefore, focuses on the molecular and cellular architecture of chemosensory communication in conspecific mammals – an innovative and interdisciplinary field of neurobiology. Combining molecular, biochemical, (electro)physiological, and live-cell imaging methods, as well as behavioral techniques in wildtype and mutant mouse models, my research challenges existing models of signal transduction in the olfactory system, analyzes the principle coding logic of pheromone detection, and, thus, sheds light on the neurophysiological basis of social behavior.

In 2006, he was awarded an Emmy Noether grant by the German Research Counsel and returned to Ruhr-University Bochum as a principal investigator. As PI, his interests focused on the largely enigmatic function of pheromones in conspecific chemical communication. In wildtype and mutant mouse models, Marc Spehr addressed questions of both pheromone detection in the periphery and pheromone processing in the brain. In 2009, he was appointed a Lichtenberg-Professor of the Volkswagen Foundation at RWTH Aachen University where his laboratory continues to study the coding logic of pheromone detection and neurophysiological basis of social behavior.

Abstract: Brain-machine interfaces (BMIs) connect the nervous system to various external devices, with the goal of restoring and/or enhancing motor, sensory and cognitive functions, and neurorehabilitation. BMIs can be used by patients with different neurological conditions as assistive devices or by healthy individuals as tools for brain augmentation. Over the past half-century, BMIs have advanced significantly from the early ideas that sounded like science fiction to the modern high-tech implementations. In particular, invasive recordings using multichannel implants have enabled real-time control of artificial limbs by nonhuman primates and human subjects. Furthermore, neural prostheses can provide artificial sensory feedback, allowing users to perceive the movements of prosthetic limbs and their haptic interaction with external objects. Recently, neuroprosthetic approach was employed to build brain-nets that incorporate several brains exchanging information or performing cooperative tasks. Notwithstanding these achievements, even more spectacular developments are expected in the future.
Biography: Mikhail Lebedev, a Senior Research Scientist at Duke University, works in the fields of Neurorophysiology and Neuroprosthetics. He received a Master's degree in Physics from Moscow Institute of Physics and Technology (1986), and a PhD in Neurobiology from the University of Tennessee, Memphis (1995). His early research was on human sensorimotor integration. Since 1991, Lebedev works in the field of primate and rodent neurophysiology; he has studied neuronal mechanisms of cortical and basal ganglia circuits. Lebedev has investigated neuronal encoding of movements, somatic sensation, spatial attention and working memory. Since 2003, Lebedev works with Miguel Nicolelis; he supervises the primate laboratory at Duke University. The major focus of his current research is on BMIs, such as BMIs for reaching and grasping, BMIs that reproduce bipedal locomotion patterns, and sensorized BMIs that both extract motor command from the brain and deliver sensory information back to the brain. Lebedev is an editor of several journals, books and special issues.

This talk focuses on how the signal processing and data analysis methodologies can be applied into the biomedical signal analysis in the data fusion framework. In our analysis, brain activities are measured through Electroencephalography (EEG) signals which were obtained from intensive care unit in hospital. In order to identify the brain consciousness states of those patients, various signal processing and predictive analytics methods were used. In this talk, some advanced methods are presented which overcomes the weakness of traditional methods in both time and frequency domains for EEG analysis. Moreover, an online signal nature tracking method based on collaborative adaptive filter is also presented in order to monitoring the brain states in real time. We then discuss how these methodologies can be further extended as a general framework for studying human biological functions and performances, ranging from hand gesture recognition to sport sciences.

Spiking neural networks (SNNs) originate from computational neuroscience, but in recent years there has been growing interest in using brain-inspired event-based computing for real-time pattern recognition. In my talk I will present novel approaches that merge ideas from SNNs and Deep Learning, the currently most successful machine learning paradigm for computer vision, speech recognition, and many real-world applications. Deep SNNs are particularly attractive for implementation in neuromorphic hardware platforms, which emulate the operation of spiking neurons in hardware, and achieve significant savings in power and latency over conventional models. New algorithmic insights allow us to reach accuracy levels that match traditional networks, while exploiting the advantages of SNNs. Deep SNNs exhibit a performance-latency tradeoff, which allows them to produce good first guesses very quickly, even before all neurons in the network are updated. I will show recent results that demonstrate how latency and computing costs in Deep SNNs can be reduced significantly, making them attractive models for fast and power-efficient information processing on power-constrained systems.

All non-invasive technologies for the study of human brain activity suffer from the requirement that only artificial, movement-constrained behavior is allowed. However, by reducing “normal” behavior to a min-imum the ecological validity of the results can be limited. To overcome these limitations, we developed a truly mobile EEG system suitable for field recordings and natural situations which allows to decode single-trial brain responses in outdoor situations. We also demonstrated that signal quality of the mobile EEG system is equivalent to that of a standard lab amplifier in a traditional BCI experiment. Besides mobility and robustness with respect to motion, the critical issue before introducing EEG routinely in large studies became the electrode, as ideal EEG electrode would allow high quality and concealed recordings that can be conveniently attached to the head. We will demonstrate that a newly introduced cEEGrid electrode concept fulfills all these requirements and allows to monitor auditory attention relia-bly over long amounts of time.
