An objective functional biomarker of retinal ganglion cell function: Applications for probing disease mechanisms

Seminar: Oxyopia Seminar | September 10 | 11:10 a.m.-12:30 p.m. | 489 Minor Hall

 Suresh Viswanathan, Associate Professor & Chair of Biological and Vision Sciences, SUNY College of Optometry

 Neuroscience Institute, Helen Wills

Work over the last decade and a half have identified and characterized a retinal ganglion cell nerve component in the flash electroretinogram. This talk will review the evidence for retinal ganglion cell origin of this potential, its mechanism of generation and applications towards understanding the pathophysiological mechanisms of glaucoma and mild traumatic brain injury.

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 >

Learning Representations for Planning

Seminar: Redwood Seminar | September 18 | 12-1 p.m. | 560 Evans Hall

 Aviv Tamar, Postdoc, UC Berkeley's Artificial Intelligence Research Lab

 Neuroscience Institute, Helen Wills

Abstract:
How can we build autonomous robots that operate in unstructured and dynamic environments such as homes or hospitals?
This problem has been investigated under several disciplines, including planning (motion planning, task planning, etc.), and reinforcement learning. While both of these fields have witnessed tremendous progress, each have fundamental drawbacks when it comes to...   More >

Ethan Bensinger's Talk Title
Dysflective Cones: Differences in Cone Reflectivity and Function in Healthy Subjects
Confocal Adaptive Optics Scanning Laser Ophthalmoscope (AOSLO) images acquired in healthy subjects reveal small areas with diminished cone reflectivity. In a survey of AOSLO images these transient hyporeflective areas of cones were found in 19 of the 80 eyes. 3 healthy subjects with...   More >

The neural circuits underlying motor planning and short-term memory

Seminar: Neuroscience Seminar | September 24 | 4-5 p.m. | 125 Li Ka Shing Center

 Karel Svoboda, Janelia Research Campus, HHMI

 Neuroscience Institute, Helen Wills

Our goal is to uncover the principles by which mammalian neural circuits perform fundamental computations, from perception to action. Cortex is parcellated into areas with distinct functions, each of which contains complex local circuits. Cortical areas in turn associate into mesoscale circuits with other cortical and subcortical areas via long-range connections. Information is represented by...   More >

A New Benchmark and Progress Toward Improved Weakly Supervised Learning

Seminar: Redwood Seminar | September 26 | 12-1 p.m. | 560 Evans Hall

 Russ Webb, Apple

 Neuroscience Institute, Helen Wills

A primary goal of this work is to give a clear example of the limits of current, deep-learning techniques and suggest how progress can be made. The presentation will include a discussion of open questions, unpublished experiments, suggestions on how to make progress. This work is founded on the paper Knowledge Matters: Importance of Prior Information for Optimization by Gulcehre et. al., which...   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 >
