The ergot alkaloid bromocriptine, given intraperitoneally produced dose-dependent, longlasting stereotyped behaviour in rats which was partly antagonised by the injection of trifluoperazine into the caudate nucleus. The stereotyped behaviour produced by apomorphine (s.c.) in both naïve and catecholamine-depleted rats was significantly enhanced by prior treatment with bromocriptine (i.p.). The bilateral application of bromocriptine (2.5–40 μg/side in either 0.5% tartaric acid or 50% propylene glycol aqueous vehicles) to the nucleus accumbens (NAC) of rats had no effect on locomotion over a 12 hr period after injection. In contrast, another ergot alkaloid, ergometrine, dissolved in the propylene glycol vehicle, and dopamine (DA) dissolved in either of the vehicles or in saline, produced marked stimulation of locomotion. As well as being inactive after direct application to the nucleus accumbens, bromocriptine (10–160 μg/side) did not induce stereotyped behaviour after bilateral injection into the caudate nucleus. However, the local application of bromocriptine (10 μg/side) to the nucleus accumbens, while itself inactive, significantly enhanced the locomotor stimulant effect of DA (5 μg/side) applied to the same nucleus. The data suggest that bromocriptine is able to enhance the effects of agonists such as DA and apomorphine at DA receptors, even under conditions where bromocriptine itself is inactive.
