A: the brain regions that comprise the cortex, striatum, and pallidum. B: the connectional relations between the triple descending projections from the cortex (green), striatum (red), and pallidum (blue), and the components in the Upper Brainstem Behavior Control Networks. Note that the predominant neurotransmitters provide for excitatory, inhibitory, and disinhibitory influences on the behavior control networks in the upper brainstem. Projections from these control networks are shown in black. Also see FIGURES 5 and 6.
