[Age alterations of monoamine oxidase activity in structures of visual analyzer as affected by light stimulation]

Light stimulation affected the monoamine oxidase activity in mitochondria of dog visual analyzer structures. The enzymatic activity was elevated as the mitochondrial fraction was increased in brain visual cortex (area 17) and in lateral geniculate body at the period from the 1 to the 21 day after birth. Light stimulation led to maximal increase in monoamine oxidase activity in the anterior colliculus of dog brain visual cortex (area 17) within 21 day after birth and in the lateral geniculate body--within the 45 day.
