The effects of microinjection of carbachol or hemicholinium into the amygdala on the levels of plasma and adrenal corticosterone in rats.
Microinjections of 0.4 microgram of carbachol into the amygdala caused a rise of corticosterone (CS) in the morning when the prestimulating level of CS was lower. But the same procedure with a larger dose had no effect in the afternoon, when the prestimulating level of CS was higher.
