[Comparative analysis of the rhythm assimilation reaction to chromatic and achromatic stimulation in children during the neonatal period].

Specificity of development of the acquisition of the rhythm of light flashes (driving) in the visual cortex depending on the light spectral composition and on age was revealed in healthy children. The index of driving for white, green and red light is minimal in the first two weeks of child's life and sharply increases in the period of 4--6 weeks. The difference between the optima of the driving reaction for green and red colors, appearing at this age, points to the development of cortical mechanisms, providing for the perception and analysis of color stimuli. In children born from diseased mothers the driving reaction is absent; chromatic stimuli cause paroxysmal activity. The significance of these parameters for early diagnosis of the cerebral functional disturbances is discussed.
