title: [Maturation and plasticity of visual system: neurogenesis, synaptogenesis, and myelogenesis. Report 2. Visual cortex and optic radiations].
abstract: Current conceptions of visual cortex synaptogenesis and mielination are reviewed. Human brain undergoes significant morphological and functional changes during prenatal period and the fist year of life that reflexes in height, latency and configuration of visual evoked potentials. The stages of neural modification are genetically predetermined, but it keeps developing under the influence of altered sensory experience. Period of accelerated development of nerve cells and formation of synaptic contacts is followed by global gradual elimination of exuberant neurons and their ineffective contacts, that promotes greater specificity of neuronal tissue and fine functional tuning. The importance of up-to-date functional and morphometric methods of brain maturation and plasticity research such as diffuse tractography is emphasized.
