The extended amygdala, like the bed nucleus of the stria terminalis (BNST), modulates worry and anxiety3,4, but additionally projects towards the ventral tegmental area (VTA) five,six, a region implicated in reward and aversion7?three, hence supplying a candidate neural substrate for integrating diverse emotional states. On the other hand, the precise functional connectivity in between distinct BNST projection neurons and their postsynaptic targets inside the VTA, at the same time as the function of this circuit in controlling motivational states haven’t been described. Right here, we recorded and manipulated the activity of genetically and neurochemically identified VTAprojecting BNST neurons in freely behaving mice.3-Hydroxypyridine-4-carboxaldehyde Chemical name Collectively, aversive stimuli exposure created heterogeneous firing patterns in VTA-projecting BNST neurons. In contrast, in vivo optically-identified glutamatergic projection neurons displayed a net enhancement of activity to aversive stimuli, whereas the firing rate of identified GABAergic projection neurons was suppressed. Channelrhodopsin-2 (ChR2) assisted circuit mapping revealed that each BNST glutamatergic and GABAergic projections preferentially innervate postsynaptic non-dopaminergic VTA neurons, thus delivering a mechanistic framework for in vivo circuit perturbations.

All authors collected, analyzed, and discussed the information.Jennings et al.Pagephotostimulation of BNST glutamatergic projections resulted in aversive and anxiogenic behavioral phenotypes. In contrast, activation of BNST GABAergic projections developed rewarding and anxiolytic phenotypes, which had been also recapitulated by direct inhibition of VTA GABAergic neurons. These information demonstrate that functionally opposing BNST to VTA circuits regulate rewarding and aversive motivational states and may serve as a vital circuit node for bidirectionally normalizing maladaptive behaviors. The ventral BNST (BNSTv) is usually a heterogen.
