[Postimperative negativity of the contigent negative variations: a critical index of a stress reaction in the normal subject?].
21 subjects were recorded during two experimental sessions: 1st session: 2 CNVs in control conditions; 2nd session: 1) control CNV, 2) CNV and arithmetic calculation, 3) CNV and labyrinthine stimulation, 4) CNV, arithmetic calculation and labyrinthine stimulation, 5) control CNV. The results obtained show a post-imperative extension of the CNV in the situation 2: arithmetic calculation (P less than 0.025) and 4: double interference (P less than 0.05).
