Development of cholinergic enzymes and atpase activity of the optic system of cats in normal and restricted visual input conditions



Development of cholinergic enzymes and atpase activity of the optic system of cats in normal and restricted visual input conditions



Developmental Neuroscience 2(1): 38-45



Developmental patterns of acetylcholinesterase (AChE), choline acetyltransferase (CAT) and ATPase activities were studied in visual centers of normally reared and binocularly deprived cats, from 1 wk-9 mo. old. The activity of these enzymes increased during postnatal development at different rates in various structures. Visual deprivation increased AChE activity in the lateral geniculate nuclei (LGN) and visual cortex by 20 and 32%, respectively, but had no effect on the superior colliculus, visual association cortex and somatosensory cortex. ATPase activity was depressed in the visual cortex of pattern-deprived cats. Visual deprivation had no effect on CAT activity and protein content in the investigated structures.
