[Maturation of evoked potentials to patterned stimuli, and sensitivity of the visual system to deprivation]

A study was made of age peculiarities of EPs to spatially structurized stimuli in the shape of chess fields with different dimensions of their cells in children and juveniles with normal vision, aged from seven to seventeen. Heterochroneity has been established in maturation of EPs to a homogeneous and a spatially structurized stimuli. In accordance with the criterion of "maturity" of the EP to a spatially structurized stimulus, an enhanced probability of "mature" EPs appearance was observed with age, from 0.23 in seven year old to 0.75 in 11 to 17 years old. Correspondence was shown of age EP dynamics to age changes of the visual system sensitivity to deprivation.
