A distinct D1-MSN subpopulation down-regulates dopamine to promote negative emotional state
文献摘要:
Dopamine (DA) level inthe nucleus accumbens (NAc) is critical for reward and aversion encoding.DA released from the ventral mesencephalon (VM) DAergic neurons increases the excitability of VM-projecting D1-dopamine receptor-expressing medium spiny neurons (D1-MSNs) in the NAc to enhance DA release and augment rewards.However,how such a DA positive feedback loop is regulated to maintain DA homeostasis and reward-averSion balance remains elusive.Here we report that the ventral pallidum (VP)projection of NAc D1-MSNs (D1NAc-VP) is inhibited by rewarding st muli and activated by averslVe stimuli.In contrast to the VM projection of D1-MSN (D1NAc-VM),activation ofD1 NAc-VP projection induces aversion,but not reward.D1NAc-VP MSNs are distinct from the D1NAc-VM MSNs,which exhibit conventional functions of D1-MSNs.Activation of D1NAc-VP projection stimulates VM GABAergic transmission,inhibits VM DAergic neurons,and reduces DA release into the NAc.Thus,D1NAc-VP and D1NAc-VM MSNs cooperatively control NAc dopamine balance and reward-aversion states.
