Role of nicotinic receptors in the lateral habenula in the attenuation of amphetamine-induced prepulse inhibition deficits of the acoustic startle response in rats.

abstract：:A neutral stimulus can acquire conditioned rewarding properties through association with an intrinsically rewarding stimulus. The acquisition of responding for conditioned rewards requires that environmental stimuli and reward processes interact in a highly specific manner; analyses of this phenomenon may provide valu...
