title: Effects of area 17 ablation on neurotransmitter parameters in efferents to area 18, the lateral geniculate body, pulvinar and superior colliculus in the cat.
abstract: The result of unilateral ablation of visual cortical area 17 in adult cats was consistent with glutamate-aspartate being the neurotransmitter in efferents to the lateral geniculate body, the pulvinar and the visual part of superior colliculus but not in efferents to area 18 and the non-visual strata of superior colliculus. Furthermore, the distribution of glutamatergic, GABAergic and cholinergic markers within the various subdivisions of the cat visual system complied well with observations made previously with biochemical, neurophysiological, histochemical and immunohistochemical methods, in this and other mammalian species.
