Certain structures of the limbic system are involved in memory, as well: two large limbic system structures, the amygdala and the hippocampus, play important roles in memory.The amygdala is responsible for determining which memories are stored and where the memories are stored in the brain.It is thought that this determination is based on how large an emotional response an event invokes. The limbic circuit links the basal ganglia ___ with areas that process emotionality such as postures and gestures and the motor expression of emotion. Other extrinsic inputs to the basal ganglia originate from the amygdala and hippocampus, which target mainly limbic striatal regions, and brainstem afferents from serotonergic, cholinergic, and noradrenergic cell groups in the raphe, PPN, and locus coeruleus, respectively.

In the adult brain input from the motor cortex to the basal ganglia comes through the striatum (neostriatum), that consists of the caudate and putamen. Interconnected brain areas called the basal ganglia (or basal nuclei) play important roles in movement control and posture. The basal ganglia, also known as basal nuclei, is a region on the underside of the brain that plays a very important role in muscle coordination and movement. Basal ganglia, amygdala, thalamus, cingulate gyrus and hypothalamus. The caudate nucleus is involved in motor processing and planning. It was formerly called nucleus accumbens septi due to its close relation to the base of septum pellucidum. The basal ganglia are subcortical nuclei that are highly developed in primates and are strongly interconnected with the neocortex.

Hemispheric specializations. Located within the basal ganglia, the caudate is thought to play a role in movement as well as learning and complex behaviors and is likely involved in the repetitive behaviors often seen in FraX.
