Our earlier experiments have shown that facilitating action of angiotensin II (AII) on recall of passive avoidance is mediated by dopaminergic systems. In an attempt to evaluate the possible site of action of AII on memory processes, bilateral lesions of the structures belonging to the limbic system, receiving efferentation from A 10 dopaminergic neurons(More)
Cholinergic agonists induce a rhythmical slow activity (RSA) in the in vitro rat hippocampus. RSA consists of bursts of activity separated by quiescent periods (interburst intervals). The activity involves activation of muscarinic receptors; however, the role of other neurotransmitter substances is still controversial. The present study demonstrates that(More)
Angiotensin II (1 microgram) dissolved in water and given intracerebroventricularly on day 1, 15 min before the first learning session, enhanced rate of learning of active avoidance in rats over the next 7 days. However, the peptide, dissolved in 0.25 M NaCl, and given at the same dose and route, stimulated learning significantly more than that dissolved in(More)
The experiments performed earlier in this Department indicated that facilitatory effect of angiotensin II (AII) on recall is connected with its influence on dopaminergic systems. In an attempt to evaluate the possible site of action of AII on the memory processes, bilateral lesion of the nucleus accumbens septi (NAS, a limbic structure which receives(More)
