[Analysis of responses to color stimulation in children with intracranial birth injury].

Premature (28) and mature (4) children who had undergone an intracranial labour trauma revealed major disturbances in the development of integrated reactions to colour stimuli and in the effect of atropine and prozerin on the pulse rate and the vegetative and EEG-components of the reactions. The extent of the disturbance and normalization of reactions, and the effect of the indicated neurotropic drugs depend on the gravity of the trauma. Maximum disturbances of the action of the drugs correspond to the period of the largest deviations from the normal in the development of integrated reactions (seven to thirteen weeks of life). The data obtained attest that the change in the development of reactions to colour stimuli in traumatized children is linked with disturbances of acetylcholin metabolism or of the cholinergic mechanisms involved in their achievement.
