Seminar: Oxyopia Seminar | April 23 | 12-1 p.m. | 489 Minor Hall


Dr. Mark Bear, PhD, PiCower Professor of Neuroscience, MIT

Neuroscience Institute, Helen Wills


Amblyopia is a prevalent form of visual disability that arises during infancy and early childhood when inputs to the visual cortex from the two eyes are poorly balanced (e.g., by misalignment of the eyes, asymmetric refraction, or opacities and obstructions of one eye). Characteristics of amblyopia are very poor acuity in one eye, and an attendant loss of stereopsis. The current standard of care...   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 >

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 >

Eavesdropping on Cortical Plasticity

Seminar: Neuroscience Seminar | June 14 | 3:30-4:30 p.m. | 125 Li Ka Shing Center


Adi Mizrahi, The Edmond and Lily Safra Center for Brain Sciences, The Hebrew University of Jerusalem

Neuroscience Institute, Helen Wills


One of the overarching goal in our lab is to understand cortical plasticity in adult circuits. This goal remains challenging because cortical neurons are functionally heterogeneous and access to specific active neurons for further experimentation is limited. In the primary auditory cortex (A1), for example, spiking responses to natural stimuli like vocalization cannot be easily predicted from...   More >

Optimal sensors in random environments

Seminar: Redwood Seminar | June 20 | 12-1:30 p.m. | 560 Evans Hall


Sarah Marzen, MIT

Neuroscience Institute, Helen Wills


The efficient coding hypothesis has revolutionized theoretical neuroscience. I would argue that it is best understood using rate-distortion theory. I use rate-distortion theory to inspire a simple model of sensory adaptation. In randomly drawn, fluctuating environments, this model suggests that neurogenesis in sensory regions is unnecessary and predicts that biological sensors are poised to just...   More >

Expression of ethanol sensitive glycine receptors in several brain regions

Seminar: Neuroscience Seminar | June 25 | 2-3:30 p.m. | 125 Li Ka Shing Center


Luis Aguayo, University of Concepcion, Chile

Neuroscience Institute, Helen Wills


Synaptic glycine receptors (GlyR) are expressed primarily in spinal cord and brain stem neurons. GlyRs are sensitive to general anesthetics, neurosteroids, Zn2+ and ethanol. Recently, GlyRs were also found in other supratentorial regions, but their properties are largely unknown. Mesolimbic regions, such as ventral tegmental area (VTA) and nucleus accumbens (nAc), were also found to express GlyRs...   More >

Correlated neural activity across the brains of socially interacting bats

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


Wujie Zhang, Yartsev Lab, UC Berkeley

Neuroscience Institute, Helen Wills


Social interaction is fundamental to our everyday life and that of diverse animals. When two animals interact, they behave in different ways. Thus, to get a full picture of the neural activity underlying each interaction, we need to record from the brains of both animals at the same time. We do so in a highly social mammal, the Egyptian fruit bat, using wireless electrophysiology, which allows...   More >

Vivek Labhishetty's Abstract
Retinal-Conjugate Surfaces: The Blur Horopter
When we fixate at an object, the image of that object is brought to sharp focus on the fovea due to the eye’s accommodation. Other objects in the periphery may be farther or nearer than best focus on those parts of the retina. We measured the shape of surface of best focus in the world as the eye accommodates to...   More >



Information decomposition

Seminar: Redwood Seminar | September 17 | 12-1 p.m. | 560 Evans Hall


Juergen Jost, MPI for Mathematics in the Sciences, Leipzig

Neuroscience Institute, Helen Wills


In many situations, two or more sources have some information about a target. For instance, sensory input and context information can jointly determine the firing pattern of a neuron. Since the information from the two sources is typically not identical, one wishes to decompose it in those parts that are unique to each source, what is shared between them and what is complementary, that is,...   More >

Repairing the brain after stroke: a biomaterials strategy

Seminar | September 26 | 12-1 p.m. | 106 Stanley Hall


Tatiana Segura, Duke University

Bioengineering (BioE)


Stroke is the leading cause of disability due to the brain’s limited capacity to regenerate damaged tissue. After stroke, an increased inflammatory and immune response coupled with severely limited angiogenesis and neuronal growth results in a stroke cavity devoid of normal brain tissue. However, stroke also induces the formation of a pro-repair/plastic region in the area adjacent to the stroke...   More >
