Interplay of beta2* nicotinic receptors and dopamine pathways in the control of spontaneous locomotion.
Acetylcholine (ACh) is a known modulator of the activity of dopaminergic (DAergic) neurons through the stimulation of nicotinic ACh receptors (nAChRs). Yet, the subunit composition and specific location of nAChRs involved in DA-mediated locomotion remain to be established in vivo. Mice lacking the beta2 subunit of nAChRs (beta2KO) display striking hyperactivity in the open field, which suggests an imbalance in DA neurotransmission. Here, we performed the selective gene rescue of functional be...Expand abstract
