“…Similar stereotyped behaviour characterized by locomotion, rearing, sniffing and gnawing is also produced by oxotremorine and other cholinergic drugs such as arecoline and physostigmine in reserpine-sedated rats (KRUGER and RANDRUP, 1968;AMBANI and WOERT, 1972). Antiparkinsonian drugs of the centrally active anticholinergic type, such as hyoscine, benactyzine, benzhexol, benztropine and caramiphen, abolish completely the stereotyped behaviour in reserpine-treated rats (KRUGER and RANDRUP, 1968).…”
