Two pathways can be distinguished, the posterior motor pathway (dark stippling with solid lines connecting the nuclei) and the anterior forebrain pathway (light stippling with dotted lines connecting the nuclei). All recordings were made in the anterior forebrain pathway, a specialized forebrain–basal ganglia circuit. HVc, high vocal center; RA, robust nucleus of the archistriatum; DLM, dorsolateral thalamic nucleus; lMAN, lateral part of the magnocellular nucleus of the anterior neostriatum; RAm, nucleus retroambigualis.
