title: Multiple unit activity recording in the corticotropic area of the deafferented hypothalamus and corticosteronemia in the pigeon.
abstract: 10 Diurnal variations in both multiple unit activity and plasma corticosterone level were suppressed after complete neural isolation of the basal hypothalamus in the pigeon. 20 It is suggested that the circadian activity of the hypothalamic pituitary corticotropic unit partially depends upon the inhibiting influence from the hippocampic-septal structures.
