Internship: Horizontal Cell Information Processing

Respond immediately

Horizontal cells are second order neurons in the retina. They can be subdivided into three types. One of those cells is assumed to be a detector for luminance (light intensity) the two other cell types are supposed to be involved in detection of color. However, this classification has never been tested quantitatively. In this electrophysiological project we will use intracellular electrodes to record responses of horizontal cells and use information theory and linear/non-linear analysis to determine how well far luminocity and color are seperated at horizontal cell level.
