title: A longitudinal CNV study in a group of five bipolar cyclothymic patients.
abstract: The authors carried out a longitudinal study in five subjects with bipolar cyclothymic psychosis, recording contingent negative variations in the same patients in the different phases of illness and under normal clinical conditions. An average voltage decrease was found in the depressive phases and a more conspicuous decrease in the manic phases. Furthermore, an evident postimperative negative variation was present in four subjects during the manic phase. The authors set forth tentative psychological and neurophysiological interpretation of their results.
