Information-theoretic analysis of turtle cortical waves

摘要

In this paper, we describe two approaches to the problem of encoding cortical waves of turtle visual cortex. The first approach relies on representing the response of individual pyramidal cells using various temporal scales (multiresolution analysis). In the second approach, we consider decomposing the visual cortex into various spatial grids. Each of these spatial grid contains several neurons and the Kullback-Leibler distance between the spiking patterns in response to different stimuli is computed. Such distance measure, we hope, would eventually be used to detect the stimuli.
