Differential behavioral response to dopamine D2 agonists by sexually naive, sexually active, and sexually inactive male rats.

abstract：:Novelty seeking refers to the tendency of humans and animals to explore novel and unfamiliar stimuli and environments. The idea that dopamine modulates novelty seeking is supported by evidence that novel stimuli excite dopamine neurons and activate brain regions receiving dopaminergic input. In addition, dopamine is s...
