ETH Zurich, Department of Health Sciences and Technology (D-HEST) Research focus: Neural algorithms and behaviour How does the brain solve complex problems? The Burdakov lab studies brain computations that convert sensory context into appropriate actions, appetites, and arousal. Our experiments focus on specific genetically-defined brain cells, but our questions are more general, overlapping with fields such as robotics (what control algorithms are best for performance in an uncertain world? what are their strengths and weaknesses?). To answer such questions, the lab studies how information is represented by specific neural clusters to sway decisions. This is achieved by tracking real-time brain network dynamics (using in vivo genetically-targeted calcium reporters, electrophysiology) associated with quantified voluntary actions, while manipulating sensory contexts (internal and external body state) and genetically- and temporally-defined elements of neural computations (using optogenetics, chemogenetics). These sensorimotor measurements are interpreted with the help of computational simulations that formally assess the performance of particular sensorimotor algorithms in defined tasks. By elucidating what different parts of the brain do, how they do it, and what makes them perform well or badly, this work provides fundamental information that can be used for designing better medical treatments for brain disorders.

Prof. Tobi Delbruck Research Focus: The sensors group at INI led by myself and PD Dr. Shih-Chii Liu develops neuromorphic silicon vison and audio sensors and methods for processing their output. These sensors and processing methods are inspired by the organizing principle of the nervous system. For instance, the brain uses spikes to transmit analog signals over long distances without losing precision by using interspike time intervals and spike coincidence to encode analog information. One of the main sensors is the dynamic vision sensor (DVS). The DVS encodes visual information by transmitting spikes in response to log intensity changes. This way, the sensor achieves very high dynamic range and can help beat the classical latency-power tradeoff suffered by conventional image sensors. We also develop many robots to demonstrate the advantages of the neuromorphic approach.

Dr. Elisa Donati, Junior Group Leader Research focus: My research activities are at the interface of neuroscience and neuromorphic engineering. My main goal is to understand how to develop event-based systems able to interface with humans to process in real-time physiological data as inputs. In particular, I am focusing on biomedical applications where the device should be implanted to restore missing biological functions, (e.g., adaptive pacemakers, biomedical devices for neuroprosthetics). In addition, I am exploring the peripherical nervous system to understand how to apply physiological models to robotic control, to build a fully event-based pipeline.

Prof. Dr. Csaba Földy Brain Research Institute, Laboratory of Neural Connectivity, University of Zurich foldy@hifo.uzh.ch Research Focus: We are interested in the role of synapses in brain function. Synapses serve as fundamental sites of information transmission between neurons, with different synapses characterized by different qualities of that transmission. Frequently, these qualities are associated with the type of neurons being connected. We reason that if synaptic transmission forms the basis of information processing in the brain, and that synaptic properties can be studied in a cell-type specific manner, we will reach a deeper understanding of the brain’s information processing by performing molecular and computational analyses of synapses, as defined by their connected cell types. In pursuit of this interest, we use electrophysiology, molecular biology, and computational modeling analyses.

Institute of Neuroinformatics, ETH Zurich Research Focus: My primary research focus is directed towards understanding the basis of information processing and memory formation in neuronal networks using experimental as well as computational approaches. Currently my research at the INI investigates basic concepts of information processing and memory formation in limbic neuronal networks, using miniaturized cutting-edge imaging techniques to record learning induced changes in neuronal network activity of mice. Aligning with the combined strengths of the INI and in collaboration biomedical and electrical engineering groups my long-term vision is to extract fundamental principles of network-learning from real biological networks and then to reverse engineer their functionality as logical, reproducible algorithms that be implemented in software or directly as electrical circuits. I am convinced that reverse-engineering neural learning algorithms that mimic human thinking will one day change the importance of intelligent technologies in our everyday life Keywords: systems and computational neuroscience, population coding, neuronal network learning, deep learning, spiking network simulations, calcium imaging, two photon microscopy, miniaturized microscope, freely moving, behavior Topic: neural basis of behavior, computation and modeling, sensory systems Projects: https://www.ini.uzh.ch/research/61357 Publications: pubmed Website: https://www.ini.uzh.ch/people/bgrewe |

Prof. Dr. Giacomo Indiveri Research Focus: Our research concerns the analysis and development of computational models, hybrid analog/digital VLSI circuits, and multi-chip event-based systems for implementing real-time distributed neural processing systems, and eventually building Neuromorphic Cognitive Systems (i.e. neuromorphic architectures that can learn and reason about the actions to take, in response to the combinations of external stimuli, internal states, and behavioral objectives). The neuromorphic cognitive systems we develop are typically real-time behaving systems comprising multi-chip, multi-purpose spiking neural architectures. They are used to validate brain inspired computational paradigms in real-world scenarios, and to develop a new generation of fault-tolerant event-based computing technologies.

Prof. Dr. Catherine Jutzeler Catherine.Jutzeler@hest.ethz.ch Research Focus: The Biomedical Data Science Lab (BMDS) is an interdisciplinary, motivated, young research team working at the intersection of medicine, data science, and biology. Our research aims to identify causes, risk factors, and biomarkers of disease progression. At the core of our research is a series of prospective and retrospective investigations that integrate genetic, biochemical, clinical assessments, and medication history with both traditional epidemiological approaches and machine-learning algorithms. Currently, we are doing research in the fields of spinal cord injury, lower back pain, and infectious diseases (e.g., sepsis in children and adults). In addition to research, we are involved in teaching activities. The major goal is to provide the students with an introduction to applied data science (programming, analysis, visualization) to solve biomedical questions.

Prof. Dr. Melika Payvand Research Focus: The question that drives us is to understand how intelligence emerges from the structure of its underlying substrate which will result in building intelligent systems. We combine the understandings from neuroscience, machine learning, and electrical engineering in a co-design fashion towards building low-power and high-density intelligent systems. We are specifically interested in building learning systems that can self-organize to the sensory information they receive. These systems have applications in a variety of autonomous sensory-motor systems and personalizing edge devices.

Prof. Dr. Rafael Polania Research Focus: Humans do not react to the environment in a reflexive manner, but can freely choose which action to perform in response to a given situation. The neural processes that enable such flexible decision making are fundamental components of human cognition and have attracted a lot of interest from researchers in many scientific disciplines such as neuroscience, psychology, economics, and medicine. The research agenda at the Decision Neuroscience Lab bridges these multiple disciplines across theoretical and empirical domains to establish important links between the computational, psychological and neural processes controlling human decision making, by providing both correlative and causal evidence that well-defined neural signals are indeed driving both computationally defined cognitive processes and the resulting behavior. This research thus has the potential to unite conceptually separate approaches to the study of distinct types of human behavior and thereby contribute information that is crucial for the diagnosis and treatment of psychiatric and neurological disorders involving decision-making pathologies (e.g. ADHD, obesity, addiction). Topics: Cognitive Neuroscience, Computation and Modeling, Neural Basis of Behavior Keywords: decision-making, EEG, fMRI, non-invasive brain stimulation, reward, perception, economics.
