Johannesburg, 1974 / The relationship between amygdaloid damage and the intmperitoneal
injection of betamethasone was studied with respect to the exploratory
behaviour of male hooded rats. Amygdalaetomy produced attenuated longterm
habituation of stimulus-specific and general exploratory behaviour.
This habituation deficit was uninfluenced by betamethasone. Betamethasone
also failed to influence long-tori. habituation in the intact animals.
Although amygdalectomy did not alter short-term habituation, betamethasone
accelerated the short-term habituation of general exploratory behaviour
in both amygdalectomised and intact animals. On replication of the
experiment betamethasone administration failed to influence exploration.
It was tentatively concluded that amygdalectomy and betamethasone influence
the habituation of exploratory activity under mutually exclusive circumstances.
However, the failure to replicate the amygdalectomy- and betamethasone-
induced changes in habituation could not be inteipreted within
the context of the present experiment.
