​Graduate Students Seminar

Seminar: Oxyopia Seminar | March 5 | 12-1 p.m. | 489 Minor Hall

Vasha Dutell, Bruno Olshausen Lab; Emilia Zin, John Flannery Lab

Neuroscience Institute, Helen Wills

Vasha Dutell’s Talk Title: Natural Visual Signals and Heterogeneous Networks Optimized to Process Them

Abstract: One of the many mysteries of the retina is its great diversity of neuron types and subtypes. An example of this is the many retinal ganglion cells subtypes that independently tile visual space, creating multiple pathways that transmit different aspects of visual information to the...   More >

Circuitry and Mathematical Codes for Navigation in the Brain

Lecture | March 5 | 4-5 p.m. | Sutardja Dai Hall, Banatao Auditorium

Ila Fiete, University of Texas at Austin

Neuroscience Institute, Helen Wills

I will review key aspects of the problem of navigation and describe the brain's circuits that participate in navigation. These circuits contain cells with remarkable responses to spatial variables, and include head-direction cells, grid cells, and place cells. I'll illustrate the head-direction circuit and code across species from insects to mammals. I'll focus on the bizzare, non-local, periodic...   More >

Peripheral Representations for computational models of Human and Machine Perception

Seminar: Redwood Seminar | March 8 | 12-1:30 p.m. | 560 Evans Hall

Arturo Deva, UC Santa Barbara

Neuroscience Institute, Helen Wills

Are there any benefits in incorporating the foveated nature of human vision into image-based metrics of perception and computer vision systems? In this talk I hope to advance our understanding of this question through my work via psychophysical experiments (eye-tracking), computational modelling, and computer vision.

The first part of the talk will revolve around peripheral representations...   More >

Dopamine Diversity: Tasks, Projections and Channels

Seminar | March 9 | 3-4 p.m. | 125 Li Ka Shing Center

Dr. Jochen Roeper, Director, Institute of Neurophysiology, Goethe University Frankfurt

Department of Molecular and Cell Biology

Dopamine (DA) midbrain neurons that in reside in the two neighboring nuclei substantia nigra (SN) and ventral tegmental area (VTA) have segregated according to their axonal projections into several mostly parallel systems with different functions in the control of action, reward-based learning and cognition. In vivo electrophysiology in awake freely moving mice demonstrates...   More >

Gaze and Locomotion in Natural Terrains

Seminar: Oxyopia Seminar | March 9 | 4-5 p.m. | 489 Minor Hall

Mary Hayhoe, Professor, Center for Perceptual Systems, University of Texas Austin

Neuroscience Institute, Helen Wills

Abstract: Eye movements in the natural world reflect the information needs of the momentary behavioral goals, the rewards and costs associated with those goals, and uncertainty about the state of the world. We examine how these factors trade off in the context of walking outdoors in terrains of varying difficulty, a situation where little is known about how visual and locomotor systems work...   More >
