Two psychiatric patient subgroups, defined on the basis of an extremely brief or an extremely prolonged electroencephalogram (EEG) response to cold pressor stimulation, also differ with regard to several aspects of autonomic response. The patients showing only a brief EEG desynchronization, with recovery during stimulation, also show a relatively brief autonomic response with recovery beginning during stimulation. They are specifically characterized by elevated levels of skin conductance throughout the measurement period. On the other hand, patients with prolonged EEG response show more prolonged autonomic response and are distinguished as a group by high heart rate levels. Clinical comparisons disclosed no diagnostic correlations. The rapid EEG and visceral recovery observed is discussed in terms of recently described neurophysiological mechanisms of homeostasis.
