In patients with Huntington’ s disease, it’ s the part of the brain called the basal ganglia that’ s destroyed. While these victims have perfectly intact explicit memory systems, they can’ t learn new motor skills. An Alzheimer’ s patient can learn to draw in a mirror but can’ t remember doing it: a Huntington ’ s patient can’ t do it but can remember trying to learn. Yet another region of the brain, an almond-size knot of neural tissue seems to be crucial in forming and triggering the recall of a special subclass of memories that is tied to strong emotion, especially fear. These are just some of the major divisions.
