Complementary Semantic Systems

Seminar: ICBS Seminar | February 3 | 11 a.m.-12:30 p.m. | 5101 Tolman Hall

Dan Mirman, University of Alabama at Birmingham

Neuroscience Institute, Helen Wills

Representing concepts in terms of semantic features, like < has 4 legs > or < is yellow >, has driven major advances in understanding semantic cognition, integrating behavioral, neural, and computational research. Feature-based approaches are very good at capturing taxonomic relations such as DOG -- BEAR, but it is less clear how they could capture thematic relations such as DOG -- LEASH, which...   More >

Optical Tools for Unraveling Whole-brain Neuronal Circuit Dynamics Underlying Behavior: From Retina to the Cortex

Seminar: Oxyopia Seminar | February 6 | 12-1:30 p.m. | 489 Minor Hall

Alipasha Vaziri, The Rockefeller University

Neuroscience Institute, Helen Wills

Optical technologies have been transformative for our current understanding of structure and function of neuronal circuits underlying behavior and are in many cases the limiting factors for pushing our understanding of the brain forward. I will discuss two different areas of research in our lab in this context.

In vision science despite of investigations for over seventy years, the absolute...   More >

Computational models of vision: From early vision to deep convolutional neural networks

Seminar: Redwood Seminar | February 6 | 4-5 p.m. | 560 Evans Hall

Felix Wichmann, University of Tübingen

Neuroscience Institute, Helen Wills

Early visual processing has been studied extensively over the last decades. From these studies a relatively standard model emerged of the first steps in visual processing. However, most implementations of the standard model cannot take arbitrary images as input, but only the typical grating stimuli used in many of the early vision experiments.

I will present an image based early vision model...   More >

A planning game reveals distributed patterning in player behavior

Seminar: Redwood Seminar | February 8 | 12-1 p.m. | 560 Evans Hall

Gautam Agarwal, Champalimaud Neuroscience Program, Portugal

Neuroscience Institute, Helen Wills

Decision-making has been modeled in great detail based on 2-alternative choice (2AC) tasks; however it remains unclear how these models apply to more naturalistic settings, where choices can have long-term and diverse consequences. In turn, quantitatively modeling more complex decisions poses a challenge, requiring adequate sampling of behavior over a larger state space. To address this problem,...   More >

The Neural Code Issue

Seminar: Redwood Seminar | February 9 | 12-1 p.m. | 560 Evans Hall

Christoph von der Malsburg, Frankfurt Institute for Advanced Studies and Platonite AG

Neuroscience Institute, Helen Wills

Let's go for the real thing: Every waking second, our mind represents for us the situation we are immersed in. How do the physical states of our brain create this mental imagery? I call this the Neural Code Issue. The pathway to solving it is currently blocked by an answer that isn't even wrong. Come to my talk if you want to get the correct one. I see it as the doorway to the realization of...   More >

Husserlian Phenomenology and Darwinian Evolutionary Biology: Complementarities, Exemplifications, and Implications

Seminar: ICBS Seminar | February 10 | 11 a.m.-12:30 p.m. | 5101 Tolman Hall

Maxine Sheets-Johnstone, University of Oregon

Neuroscience Institute, Helen Wills

Descriptive foundations and a concern with origins are integral to both Husserlian phenomenology and Darwinian evolutionary biology. The complementary aspects are rooted in the lifeworld as it is experienced. Detailed specifications of the complementary aspects testify to a mutual relevance of phenomenology to evolutionary biology and of evolutionary biology to phenomenology. Exemplifications of...   More >

Building a Platform for Machine Intelligence

Seminar: Oxyopia Seminar | February 13 | 12-1:30 p.m. | 489 Minor Hall

Amir Khosrowshahi, Intel Corporation

Neuroscience Institute, Helen Wills

Deep learning is now state-of-the-art across a wide variety of machine learning domains including speech, video, and text. Nervana is a startup providing deep learning as a platform. Nervana’s core technology is a novel processor architecture for deep learning providing an enabling increase in speed, scale, and efficiency. I will talk about some of our engineering and early efforts in working on...   More >

Temporal Coding and the Perception of Musical Harmony: Berkeley Ear Club

Colloquium | February 21 | 4 p.m. | Tolman Hall, 3201/ Warner Brown Room

Chris Plack, University of Machester, UK

Department of Psychology

Chris Plack, University of Manchester
Temporal fluctuations in sounds are represented by the synchronized firing patterns of neurons in the auditory nerve and auditory brainstem. These patterns can be measured in humans using electroencephalography, and are reflected in a sustained response called the “frequency-following response” (FFR). When two musical notes with simple frequency ratios are...   More >

Two-photon Imaging and Manipulation of Cortical Neural Circuits in vivo

Seminar | February 27 | 4-5 p.m. | Soda Hall, HP Auditorium (306)

Weijian Yang, Postdoctoral Research Scientist, Columbia University

Electrical Engineering and Computer Sciences (EECS)

One challenge of understanding how the brain works is the complexity of neural circuits. Optical methods provide a route to record and manipulate the neural activity of a small subset of neuron cells with cellular resolution. In this talk, I will discuss our approach to tackling the above challenges through novel three-dimensional (3D) imaging and optical manipulation methods.

Two-photon Imaging and Manipulation of Cortical Neural Circuits in vivo

Seminar: Neuroscience Seminar | February 27 | 4-5 p.m. | 306 Soda Hall

Weijian Yang, Columbia University

Neuroscience Institute, Helen Wills

One challenge of understanding how the brain works is the complexity of neural circuits. These circuits are composed of hundreds of thousands of neurons that are interconnected in a highly distributed fashion. Optical methods provide a route to record and manipulate the neural activity of a small subset of these cells with cellular resolution. The desire to access a larger volume with higher...   More >
