Abstract
Presentation Description :
The visual processing properties of most of the 20+ retinal ganglion cell (RGC) types in the primate retina remain unknown. Using large-scale high-density multi-electrode recordings from macaque and human retinas, we reveal some of the basic spatial, temporal and chromatic response properties of 10+ novel RGC types that have been studied little or not at all, as well as a similar number of novel polyaxonal amacrine (PAC) cell types. Cell type identification is performed by quantitative clustering of stereotyped visual response properties, and confirmed by the mosaic organization of each identified type. The results reveal surprisingly diverse receptive field structure of novel RGC and PAC types, and high similarity between novel macaque and human cell types.
