dc.description.abstract | Previous studies have shown that ra'ss positive, palatability-dependent consummatory reactions to infused tastes are selectively facilitated by a benzodiazepine agonist (chlordiazepoxide), and that this effect can be blocked by the coadministration of benzodiazepine antagonists (e.g., Ro 15-1788). The purpose of the present study was to determine whether agents acting at other receptor sites (dopaminergic, serotonergic), which have been shown to modulate food consumption, might also modify rats' palatability-dependent reactivity to infused tastes. In this experiment, the benzodiazepine agonist, diazepam, facilitated positive palatability reactions, while dopaminergic agents (haloperidol, apomorphine, amphetamine) had no significant effects on either positive or aversive reactions. The putative 5-HT1A agonists, buspirone and gepirone, had a general inhibitory action on both positive and aversive palatability reactions. These results are surprising in view of the effects of serotonergic and dopaminergic agents on food and fluid intake. Our results suggest that the benzodiazepine receptor system may play a special role in the neural control of appetite through its enhancement of the positive palatability of tastes. Dopamine systems, by contrast, appear to control food intake by modulating processes that are independent of food affect evaluation. | en_US |
