Summary diagram to demonstrate the GABAergic and glutamatergic phenotype in neurons projecting from hypothalamic regions to the ventral tegmental area (VTA). (A) In addition to the major GABAergic (from the NAc and RMtg) and glutamatergic (from the LHb and LDtg) inputs, the hypothalamus (enframed) also represents a significant source of GABAergic and glutamatergic afferents to the VTA. The hypothalamic nuclei and regions demonstrated in two paramedian sagittal sections (B = L 0.18 and C = L 1.13 mm) are color-coded to illustrate the relative ratio of GAD65 (red) and VGLUT2 (green) expressing neurons. The white color shows the relative ratio of neurons, which either do not express these markers or express them below the detection threshold of ISHH.
