A novel touchscreen-automated paired-associate learning (PAL) task sensitive to pharmacological manipulation of the hippocampus: a translational rodent model of cognitive impairments in neurodegenerative disease.

abstract：:Using a conditioned avoidance procedure in rats, the present study examined the ability of 8-OH-DPAT, ritanserin, and prazosin to alter the effects of the dopamine antagonists, raclopride and haloperidol, on avoidance- and on escape responding. The 5-HT1A agonist 8-OH-DPAT (0.16 mg/kg) significantly enhanced the inhib...
