Final answer:
The basal nuclei are located deep within the cerebral hemispheres and include structures like the caudate, putamen, and globus pallidus, while the limbic system, encompassing the hippocampus and amygdala, surrounds the brainstem and is involved in emotion and memory.
Step-by-step explanation:
Anatomically, the basal nuclei are not located in the brainstem, cerebellum, or among the thalamus but are deep within the cerebral hemispheres. They include the caudate, putamen, and globus pallidus, which are collectively important in controlling movement and are involved in the modulation of motor commands through their interaction with the cortex and thalamus. On the other hand, the limbic system surrounds the brainstem and includes structures like the hippocampus and amygdala, which are involved in emotion and memory processing.
