The Stabilized Supralinear Network, or, The Importance of Being Loosely Balanced (Miller) / Spatiotemporal profiles of spiking variability in recurrent networks (Doiron)

Seminar: Redwood Seminar | August 15 | 12-1:30 p.m. | 560 Evans Hall

Ken Miller, Columbia University; Brent Doiron, University of Pittsburgh

Neuroscience Institute, Helen Wills

Miller: I will describe the Stabilized Supralinear Network mechanism and its application to understanding sensory cortical behavior. The mechanism is based on a network of excitatory (E) and inhibitory (I) neurons with very simple assumptions: (1) Individual neurons have an expansive or supralinear input/output functions, e.g. a power law with power >1; (2) Feedback inhibition is sufficiently...   More >

Discovering Relationships and their Structures Across Disparate Data Modalities

Seminar: Redwood Seminar | August 17 | 12-1:30 p.m. | 560 Evans Hall

Joshua Vogelstein, Johns Hopkins University

Neuroscience Institute, Helen Wills

Determining whether certain properties are related to other properties is fundamental to scientific discovery. As data collection rates accelerate, it is becoming increasingly difficult yet ever more important to determine whether one property of data (e.g., cloud density) is related to another (e.g., grass wetness). Only if two properties are related are further investigations into the geometry...   More >
