Effects of brief monocular deprivation on binocular depth perception in the cat: a sensitive period for the loss of stereopsis.

abstract：:We have developed two brain slice preparations for studying tectofugal visual pathways in the chick: conventional, 400-microns slices ("thin slices"), and "thick slices" which encompass the rostral pole of the optic tectum and the contralateral optic nerve. Stimulation was delivered with a bipolar electrode positioned...

abstract：:GABA is a major inhibitory neurotransmitter in the mammalian retina and it acts at many different sites via a variety of postsynaptic receptors. These include GABAA receptors and bicuculline-resistant GABAC receptors. The release of acetylcholine (ACh) is inhibited by GABA and strongly potentiated by GABA antagonists....
