​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 >

Beyond New Neurons: The Secretory Role of Adult Hippocampal Stem and Progenitor Cells

Seminar: Neuroscience Seminar | March 12 | 9-10:30 a.m. | 445 Li Ka Shing Center

Dr. Liz Kirby, Assistant Professor at OSU

Neuroscience Institute, Helen Wills

In the adult mammalian hippocampus, resident neural stem and progenitor cells give rise to new, highly plastic neurons. A great deal of research has focused on the role of these new neurons in supporting hippocampal memory function and injury response. However, our recent work shows that undifferentiated neural stem and progenitor cells also have functional relevance by secreting soluble...   More >

Comparative Neurobiology of Social Bonds - from Rodents to Primates to Humans

Colloquium | March 12 | 12:10-1:10 p.m. | 3105 Tolman Hall

Karen Bales, Department of Psychology, UC Davis

Department of Psychology

Social bonds are critical to human health and well-being. However, most of what we know regarding the neurobiology of strong, selective social bonds ("pair-bonds") comes from a socially monogamous rodent, the prairie vole. In my laboratory, we also study a socially monogamous primate, the titi monkey, as a model for the neurobiology of pair bond formation and maintenance. We have characterized...   More >

Core Cognitive Mechanisms in Learning and Development

Colloquium | March 12 | 3-4:30 p.m. | 5101 Tolman Hall

Celeste Kidd, Assistant Professor, Brain and Cognitive Sciences, Center for Visual Science, University of Rochester

Neuroscience Institute, Helen Wills

The talk will discuss approaches aimed at understanding the computational mechanisms that drive learning and development in young children. Although infants are born knowing little about the world, they possess remarkable learning mechanisms that eventually create sophisticated systems of knowledge. We discuss recent empirical findings about learners’ cognitive mechanisms—including attention,...   More >

Science Lecture - Unlocking the secrets of brain aging

Lecture | March 17 | 11 a.m.-12:30 p.m. | 100 Genetics & Plant Biology Building

Daniela Kaufer, Neuroscience & Integrative Biology


Aging can involve a decline in neural function that impairs cognition and contributes to neurological diseases. However, the biological mechanisms that cause the transition from a young-and-healthy to aged-and-dysfunctional brain are not well understood. In this talk, Dr. Kaufer will describe recent findings from her lab which identified a novel mechanism underlying this transition. She will also...   More >

Seeing where we’re going: a retinal code for self-motion

Seminar: Oxyopia Seminar | March 19 | 12-1 p.m. | 489 Minor Hall

Dr. David Berson, Professor of Medical Science, Chair of NeuroScience, Brown University

Neuroscience Institute, Helen Wills

Abstract: Self-motion triggers complementary visual and vestibular reflexes supporting image-stabilization and balance. Translation through space produces one global pattern of retinal image motion (optic flow), rotation another. We show that each subtype of direction-selective ganglion cell (DSGC) adjusts its direction preference topographically to align with specific translatory optic flow...   More >

Spike inference for genetically encoded calcium indicators with models of multistep binding kinetics

Seminar | March 19 | 4-5:30 p.m. | 177 Life Sciences Addition

Dr. David Greenberg, Center of Advanced European Studies and Research, Bonn, Germany

Neuroscience Institute, Helen Wills

Multiphoton imaging of genetically encoded calcium indicators can detect action potential (AP) evoked fluorescence changes from populations of spatially resolved neurons, but the nonlinear dependence of fluorescence on AP counts and variable indicator expression across neurons make quantitative inference problematic. We developed a biophysical model of GCaMP6s in neurons based on the...   More >

Grounds for Science-The deceptiveness of perception

Presentation | March 23 | 6:30-8 p.m. |  Scarlet City Espresso Bar

3960 Adeline, Emeryville, CA 94608

Dylan Paiton, Vision Science Graduate Group


Optical illusions and visual hallucinations are highly unusual. How is it that we are able to see something that is not really there? Dylan will outline standard methods that neuroscientists use to better understand how our brains process light, and introduce a theory for conscious vision that has guided decades of computational and experimental neuroscience.

“Stability and Flexibility in Motor Networks”

Seminar | March 28 | 12-1 p.m. | 106 Stanley Hall

Michael Long, New York University School of Medicine

Bioengineering (BioE)

For us to interact with the outside world, our brains must plan and dictate our actions and behaviors. In many cases, we learn to reproducibly execute a well-defined series of muscle movements to perform impressive feats, such as hitting a golf ball or playing the violin. In other cases, however, we are required to adjust our behavior to account for uncertain sensory information from the world...   More >
