Schematic of the major presynaptic inputs to PZ GABAergic neurons. Color scale represents the percentage of total inputs. BST, bed nucleus of the stria terminalis; DpMe, deep mesencephalic nucleus; IRt, intermediate reticular nucleus; LH, lateral hypothalamic area; LV, lateral ventricle; M1, primary motor cortex; M2, secondary motor cortex; Med, medial (fastigial) cerebellar nucleus; PnO, pontine reticular nucleus, oral part; SNR, substantia nigra, pars reticulata; ZI, zona incerta.
