Plasma corticosterone response level showed a smaller rise in lactating than nonlactating female rats exposed to a strange environment. The hypothalamic CRF activity of lactating females did not differ from that of the nonlactating in unstressed conditions. After placement of both lactating and nonlactating female rats in a strange environment for one hour, the hypothalamic CRF activity of nonlactating animals showed a significant decrease which could not be observed in lactating rats. Moreover, it was found that the diurnal rhythm of plasma corticosterone concentration is almost absent in lactating animals.
