Reduce, reuse, recycle your vision: the basis of rich and stable perceptual experience

Lecture | March 6 | 3:15 p.m. | Alumni House, Toll Room

 David Whitney, Professor, UC Berkeley, Department of Psychology

 Department of Psychology

The visual world is cluttered, discontinuous, and noisy, but our perceptual experience is not—scenes appear rich, seamless, and stable. This seeming contradiction has posed a challenge for theories of perception for decades. In this talk, I will discuss two complementary processes that reconcile the contradiction: First, a mechanism that generates rich visual impressions by efficiently...   More >

Astrocytes Accumulate Evidence that Actions are Futile and Trigger Behavioral State Switches in Zebrafish

Seminar: Redwood Seminar | March 8 | 2-3:30 p.m. | 560 Evans Hall

 Misha Ahrens, HHMI Janelia Research Campus

 Neuroscience Institute, Helen Wills

When a behavior repeatedly fails to achieve its goal, animals often give up and become passive, which can be strategic for preserving energy or regrouping between attempts. It is unknown how the brain identifies behavioral failures and mediates this behavioral state switch. In larval zebrafish swimming in virtual reality, visual feedback can be withheld so that swim attempts fail to trigger...   More >

Biology as information dynamics

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

 John Baez, UC Riverside

 Neuroscience Institute, Helen Wills

If biology is the study of self-replicating entities, and we want to understand the role of information, it makes sense to see how information theory is connected to the ‘replicator equation’ — a simple model of population dynamics for self-replicating entities. The relevant concept of information turns out to be the information of one probability distribution relative to another, also known as...   More >

 Earl K. Miller, Picower Professor of Neuroscience, MIT

 Neuroscience Institute, Helen Wills

Working memory is the fundamental function by which we break free from reflexive input-output reactions to gain control over our own thoughts. It has two types of mechanisms: online maintenance of information and its volitional or executive control. Classic models proposed persistent spiking for maintenance but have not explicitly addressed executive control. I will review recent theoretical and...   More >

With accumulating evidence to suggest that light exposure and...   More >

Social Curiosity and Social Learning

Colloquium | April 8 | 12:10-1:30 p.m. | 1102 Berkeley Way West

 Hyo Gweon, Stanford University, Department of Psychology

 Department of Psychology

Learning does not occur in isolation. From parent-child interactions to formal classroom environments, humans explore, learn, and communicate in rich, diverse social contexts. Rather than simply observing and copying their conspecifics, humans engage in a range of epistemic practices that actively recruit those around them. They query others to acquire useful information, consider others’ mental...   More >

Mechanisms of experience-dependent plasticity in GABAergic circuits: connecting genes to cell-types and circuit-functions

Complexity of linear regions in deep networks

Seminar: Redwood Seminar | April 24 | 12-1:30 p.m. | 560 Evans Hall

 David Rolnick, University of Pennsylvania

 Neuroscience Institute, Helen Wills

It is well-known that the expressivity of a neural network depends on its architecture, with deeper networks expressing more complex functions. For ReLU networks, which are piecewise linear, the number of distinct linear regions is a natural measure of expressivity. It is possible to construct networks for which the number of linear regions grows exponentially with depth. However, we show that...   More >

Optical coherence tomography (OCT) and adaptive optics scanning light ophthalmoscopy (AOSLO) have become invaluable tools for mapping the ultrastructure of the retina in living humans. OCT imaging has revealed considerable variation in retinal layer thickness, foveal shape and morphology. AOSLO imaging has revealed large variation in cone mosaics, both peak and eccentricity dependence density...   More >

A globally growing prevalence of myopia has led to increasing investigation and development of optical corrections which slow its progression. Overnight orthokeratology (OK, also known as corneal reshaping) and multifocal soft contact lenses (MFSCLs) show the most consistent results for reducing axial and refractive progression in childhood myopia, by around 50%, with only some understanding of...   More >

It is a truth not yet universally acknowledged that a self-regulating system which is stable in one environment can become unstable when the environment changes. This truth is called homeostatic fragility. Mathematically, the key mechanism is sign-reversal, which converts a negative-feedback loop into a positive-feedback loop. Sign-reversal explains all sorts of self-regulatory malfunctions in...   More >

Why Do Line Drawings Work?

A long-standing puzzle in perception is the question: why is it so easy for us to understand shape in line drawings, even though they do not correspond to any real-world percept? Past theories have been unsatisfactory, for example, hypothesizing that line drawings are a culturally-specific learned language, or that line drawings “trick” V1 into treating lines as step edges at object contours. I...   More >
