Dynamic Fading Memory and Expectancy Effects in Monkey Primary Visual Cortex

|
By Yiling Yang, Johanna Klon-Lipok, Katharine A. Shapcott, Andreea Lazar
| BioRxiv
Abstract In order to investigate the involvement of primary visual cortex (V1) in working memory (WM), parallel, multisite recordings of multiunit activity were obtained from monkey V1 while the animals performed a delayed match-to-sample (DMS) task. During the delay period, V1 population firing rate vectors maintained a lingering trace of the sample stimulus that could be reactivated by intervening impulse stimuli that enhanced neuronal firing.

Paying attention to natural scenes in area V1

Abstract Natural scene responses in the primary visual cortex are modulated simultaneously by attention and by contextual signals about scene statistics stored across the connectivity of the visual processing hierarchy. Here, we hypothesized that attentional and contextual top-down signals interact in V1, in a manner that primarily benefits the representation of natural visual stimuli, rich in high-order statistical structure.
