Abstract:Sniffing is a motivated behavior displayed by all terrestrial vertebrates on the planet. While sniffing is associated with acquiring and processing odors, sniffing is also intertwined with affective and motivated states. The neuromodulatory systems which influence the display of sniffing are unclear. Here, we report that dopamine release into the ventral striatum, with exception of the nucleus accumbens core, is coupled with bouts of sniffing and that stimulation of dopaminergic terminals in those regions init… Show more
