This retarding effect of stimulus pre-exposure is called latent inhibition (LI) and is reliably disrupted by amphetamine, antipsychotics having an opposite effect. The present experiments investigated whether agents which affect serotonergic transmission also attenuate LI, using a conditioned suppression of drinking procedure. The results showed that the 5-HT\n                    <jats:sub>2<\/jats:sub>\n                    antagonist ritanserin (2.0 mg\/kg), and the 5-HT\n                    <jats:sub>1b<\/jats:sub>\n                    agonist RU 24969 (0.5 and 10.0 mg\/kg) attenuated LI by increasing learning in pre-exposed animals, whilst the effects of the 5-HT\n                    <jats:sub>1a<\/jats:sub>\n                    agonist 8-OH-DPAT (0.38 mg\/kg), though in a similar direction, were not significant. These experiments provide partial support for the involvement of serotonin in LI. Since amphetamine-induced attenuation of LI has been proposed as a model for the attentional deficits found in acute schizophrenia, these results are discussed in terms of the possible involvement of reduced serotonergic function in schizophrenic attentional disorder.\n
