=== Limbic loop ===
The “limbic loop” is very similar to the direct pathway motor loop of the [[basal ganglia]]. In both systems, there are major excitatory inputs from the cortex to the striatum (accumbens nucleus), the midbrain projects neuromodulatory dopamine neurons to the striatum, the striatum makes internuclear connections to the pallidum, and the pallidum has outputs to the thalamus, which projects to the cortex, thus completing the loop. The limbic loop is distinguished from the motor loop by the source and nature of the cortical input, the division of the striatum and pallidum that process the input, the source of the dopaminergic neurons from the midbrain, and the thalamic target of the pallidal output.
The ''limbic loop'' controls [[cognitive]] and [[affective]] functioning and the motor loop controls movement.
