Drug-induced stereotypes and asymmetric behaviour after substantia nigra pars posterior (SNPP) lesions in cats.

Apomorphine- (Apo) and amphetamine- (Amph) induced behavioural phenomena were studied in cats which received either 6-hydroxydopamine (6-OHDA) or electrothermic lesions of the posterior part of the substantia nigra (SNPP). In this species, as in rats, both drugs evoked sterotypies (sniffing and head nodding) and an enhancement of locomotor activity. However… CONTINUE READING
