The hippocampus plays important roles in consolidation of information from short-term memory to long-term memory, and in spatial memory that enables navigation.
In Alzheimer's disease (and other forms of dementia), the hippocampus is one of the first regions of the brain to suffer damage; short-term memory loss and disorientation are included among the early symptoms.
The insulae are believed to be involved in consciousness and play a role in diverse functions usually linked to emotion or the regulation of the body's homeostasis.
