An in vitro study of retinotectal transmission in the chick: role of glutamate and GABA in evoked field potentials.

abstract：:It is widely accepted that human color vision is based on two types of cone-opponent mechanism, one differencing L and M cone types (loosely termed "red-green"), and the other differencing S with the L and M cones (loosely termed "blue-yellow"). The traditional view of the early processing of human color vision sugges...
