The peripheral and central nervous systems have numerous examples of two or more neuroactive products co-existing in the same neuron[1],which can simultaneously be released as both fast-acting neurotransmitters and slow-acting regulatory neuropeptides[2].For example,neurons in the lateral hypothalamus(LH)release both irritant neurotensin(Nts)and inhibitory-aminobutyric acid(GABA),two counterproductive substances[3].LH-Nts neurons project to the ventral tegmental area(VTA)and form synaptic connections with dopamine(DA)neurons to regulate reward[4-6].More critically,VTA-DA neurons express the Nts receptor Ntsrl and play a crucial role in cognition,anesthesia,reward,and disgust[4,7,8].Nevertheless,a mechanistic understanding of how stimulation and inhibition work together to control the output of neural circuits remains *** is very difficult to selectively isolate these signaling pathways in cell and circuit-specific manners.
