AMPA-selective glutamate receptor subunits GluR2 and GluR4 in the cat retina: an immunocytochemical study.

abstract：:We recorded the responses of neurons from the cat's lateral geniculate nucleus to drifting sine-wave grating stimuli both before and during electrical stimulation of the parabrachial region of the midbrain. The parabrachial region provides a mostly cholinergic input to the lateral geniculate nucleus, and our goal was ...
