Dorsal Raphe Dopamine Neurons Represent the Experience of Social Isolation
The motivation to seek social contact may arise from either positive or negative emotional states, as social interaction can be rewarding and social isolation can be aversive. While ventral tegmental area (VTA) dopamine (DA) neurons may mediate social reward, a cellular substrate for the negative affective state of loneliness has remained elusive. Here, we identify a functional role for DA neur...
متن کاملD2-like dopamine receptors depolarize dorsal raphe serotonin neurons through the activation of nonselective cationic conductance.
The dorsal raphe (DR) receives a prominent dopamine (DA) input that has been suggested to play a key role in the regulation of central serotoninergic transmission. DA is known to directly depolarize DR serotonin neurons, but the underlying mechanisms are not well understood. Here, we show that activation of D2-like dopamine receptors on DR 5-HT neurons elicits a membrane depolarization and an i...
متن کاملA glutamatergic reward input from the dorsal raphe to ventral tegmental area dopamine neurons
Electrical stimulation of the dorsal raphe (DR) and ventral tegmental area (VTA) activates the fibres of the same reward pathway but the phenotype of this pathway and the direction of the reward-relevant fibres have not been determined. Here we report rewarding effects following activation of a DR-originating pathway consisting of vesicular glutamate transporter 3 (VGluT3) containing neurons th...
متن کاملSerotonin neurons in the dorsal raphe nucleus encode reward signals.
The dorsal raphe nucleus (DRN) is involved in organizing reward-related behaviours; however, it remains unclear how genetically defined neurons in the DRN of a freely behaving animal respond to various natural rewards. Here we addressed this question using fibre photometry and single-unit recording from serotonin (5-HT) neurons and GABA neurons in the DRN of behaving mice. Rewards including suc...
متن کاملPresynaptic Partners of Dorsal Raphe Serotonergic and GABAergic Neurons
The serotonin system powerfully modulates physiology and behavior in health and disease, yet the circuit mechanisms underlying serotonin neuron activity are poorly understood. The major source of forebrain serotonergic innervation is from the dorsal raphe nucleus (DR), which contains both serotonin and GABA neurons. Using viral tracing combined with electrophysiology, we found that GABA and ser...
