Electrodermal orienting response, maternal age, and season of birth in schizophrenia

Consistent with earlier research, male schizophrenic patients born during the season of excess risk for schizophrenia (January-April) showed significantly lower electrodermal responsivity than controls born during the season of excess risk, and patients and controls born during the season not associated with increased risk (May-December). No support for maternal age as an explanation for the season-of-birth effect was found.
