Fig. 1. Behavioral functions of the projections of GABAergic and glutamatergic BNST neurons.

Summary of the causal roles of the efferent projections from BNST^Vgat and BNST^Gad2 neurons (left) and BNST^Vglut2 neurons (right). RTPP, real-time place preference; self-stim, self-stimulation; RTPA, real-time place aversion. Note that different circles and arrows do not indicate that separate subpopulations of neurons project to each target area. The anatomical relationship among the projections remains unclear, except that the BNST neurons projecting to the PAG and LH are distinct.
