Laminar processing of feedforward and feedback signals in visual cortex
Affiliation: Netherlands Institue for Neuroscience
Abstract: The neocortex of mammals is arranged into 6 layers and we have a good understanding of the anatomical connections of cells in the different layers. We still however lack a clear understanding of the functions of different layers and how information is passed through laminar circuits. In this talk, I will explore how feedforward visual processes, such as the generation of receptive-field tuning, and feedback processes such as figure-ground modulation, attentional selection and working memory activate the different layers of the primary visual cortex. I will discuss work in mice, monkeys and humans and relate the electrophysiological data in animal models to the growing field of laminar fMRI.
