title: [Fenamin stereotypy as a stable rhythmic process].
abstract: In cats with amphetamine stereotypy, the rate of horizontal head movements ranges rhythmically in time. Marked stereotypy is in agreement with more regular and low amplitude waves on the total activity curve. During amphetamine effect abatement, the curve gets stabilized as regards the amplitude and period. According to the results of separate evaluation of the temporary dynamics of the number of the left- and right-handed head movements, stereotypy is marked by an increase in the period duration when the rate of the movements changes differently. Natural or neuroleptic-induced abatement of stereotypy is accompanied by an increase in the duration of unidirectional (synchronized) shifts of the rate of the head movements.
