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 >

Adversarial Examples that Fool both Computer Vision and Time-Limited Humans

Seminar: Redwood Seminar | November 7 | 12-1 p.m. | 560 Evans Hall


Gamaleldin Elsayed, Google Brain

Neuroscience Institute, Helen Wills


Machine learning models are vulnerable to adversarial examples: small changes to images can cause computer vision models to make mistakes such as identifying a school bus as an ostrich. However, it is still an open question whether humans are prone to similar mistakes. Here, we address this question by leveraging recent techniques that transfer adversarial examples from computer vision models...   More >

Neurocomputational mechanisms underlying social norms and controllability

Colloquium | November 28 | 10:30 a.m.-12 p.m. | 1104 Berkeley Way West


Xiaosi Gu, Icahn School of Medicine at Mount Sinai

Neuroscience Institute, Helen Wills


To maintain the normal functioning of a society, individuals must be able to learn to adapt to norms. Neuroimaging studies have suggested that the ventromedial prefrontal cortex (vmPFC) and the insular cortex might be important for norm learning. However, norms are not static processes but rather, can be changed and updated if individuals of a society learn to act on them. In other words, the...   More >
