Excitatory glutamate inputs from other limbic structures amygdala, hippocampus and the prefrontal cortex facilitate dopaminergic activity in the VTA and NAc [ 62 ]. The hypothalamic nuclei that facilitate erections receive pro-erectile input from the mesolimbic dopamine pathway, which comprises the ventral tegmental area VTA and the nucleus accumbens NAc [ 62 ].
