Christopher Logan Chariker

Assistant Research Professor of Mathematics
Mathematics

Overview


My research is at the interface between dynamical systems and computational neuroscience. I work with networks of interacting neurons viewed as large and complex dynamical systems. My interests range from rigorous analysis of toy models of neuronal populations to large-scale computational models that are biologically realistic.

A Computational Model of Direction Selectivity in Macaque V1 Cortex Based on Dynamic Differences between On and Off Pathways.

Journal Article The Journal of neuroscience : the official journal of the Society for Neuroscience · April 2022 This paper is about neural mechanisms of direction selectivity (DS) in macaque primary visual cortex, V1. We present data (on male macaque) showing strong DS in a majority of simple cells in V1 layer 4Cα, the cortical layer that receives direct afferent in ... Full text Open Access Cite
