Biophysics Seminar

Thursday, February 21st 2019
10:10 am:
Biophysics Seminar in 120 PAN
Speaker: Gordon Smith, Assistant Professor, Department of Neuroscience, UMN
Subject: Development of large-scale networks in visual cortex.

Sensory perception requires the coordinated activity of tens of thousands of neurons, working together in large-scale networks. As developmental events define and constrain the ultimate capabilities of these networks, it is therefore essential to understand the mechanisms underlying their formation. This talk will present recent work showing that in the developing visual cortex, correlations in spontaneous neural activity define large-scale functional networks with precise local and long-range organization that span millimeters of cortical area. These early networks predict future stimulus-evoked activity well before it can be visually driven, suggesting they form a substrate for building a mature large-scale functional architecture.
