title: [Morphofunctional types of rabbit visual cortex neurons during postnatal ontogeny].
abstract: Eight types of unit responses to flashes were singled out in the visual cortex of non-immobilized rabbits, with morphological identification of representatives of each type. Inhibition was predominant in pyramids responses. Two types of non-pyramid neurones were revealed: with an early excitation (reception of afferent impulses) and with a delayed activation (recurrent inhibition). The distribution of responses along the cortical depth confirms the concept of vertical organization in the functional specialization of neurones. In postnatal ontogenesis there occurs the maturation of stellate cells and the substitution of the immature mechanisms of responses (on pyramid neurones) with normal ones (involving all neuronal types).
