Perturbation and Control of Human Brain Network Dynamics

Seminar | May 3 | 3:30-4:30 p.m. | 101 Life Sciences Addition

Dani Bassett, University of Pennsylvania

Neuroscience Institute, Helen Wills

Abstract: The human brain is a complex organ characterized by heterogeneous patterns of interconnections. New non-invasive imaging techniques now allow for these patterns to be carefully and comprehensively mapped in individual humans, paving the way for a better understanding of how wiring supports our thought processes. While a large body of work now focuses on descriptive statistics to...   More >

Title: The Secret Lives of Retinal Astrocytes
Abstract: The study of glia – the support cells of the central nervous system – has come a long way since Rudolf Virchow described a connective tissue of the brain that he termed ‘nervenkitt’ in 1856. Rather than a passive scaffolding for neurons (the word ‘glia’ means glue in Greek), these cells are responsible for a...   More >

Expander graph architectures for high-capacity neural memory

Seminar: Redwood Seminar | May 22 | 12-1:30 p.m. | 560 Evans Hall

Rishidev Chaudhuri, UT Austin/Simons Institute UC Berkeley

Neuroscience Institute, Helen Wills

Memory networks in the brain must balance two competing demands. On the one hand, they should have high capacity to store the large numbers of stimuli an organism must remember over a lifetime. On the other hand, noise is ubiquitous in the brain and memory is typically retrieved from incomplete input. Thus, memories must be encoded with some redundancy, which reduces capacity. Current neural...   More >

Characterizing neurons in the visual area V4 through interpretable machine learning

Seminar: Redwood Seminar | May 23 | 12-1:30 p.m. | 560 Evans Hall

Reza Abbasi-Asl, UC Berekely

Neuroscience Institute, Helen Wills

In the past decade, research in machine learning has been exceedingly focused on the development of algorithms and models with remarkably high predictive capabilities. Models such as convolutional neural networks (CNNs) have achieved state-of-the-art predictive performance for many tasks in computer vision, autonomous driving, and transfer learning in areas such as computational neuroscience....   More >

Inference and Efficient Coding in Natural Auditory Scenes

Seminar: Redwood Seminar | May 30 | 12-1:30 p.m. | 560 Evans Hall

Wiktor Mlynarski, MIT

Neuroscience Institute, Helen Wills

Processing of natural stimuli in sensory systems has been traditionally studied within two theoretical frameworks: probabilistic inference and efficient coding. Probabilistic inference specifies optimal strategies for learning about relevant properties of the environment from local and ambiguous sensory signals. Efficient coding provides a normative approach to study encoding of natural stimuli...   More >
