Hippocampus anatomy These limbic structures include the hippocampus, cingulate cortex, olfactory cortex, and amygdala. Paul MacLean once suggested, as part of his triune brain theory, that the limbic structures constitute the neural basis of emotion. While most neuroscientists no longer believe in the concept of a unified "limbic system", these regions are highly interconnected and do interact with one another. Starting at the dentate gyrus and working inward along the S-curve of the hippocampus means traversing a series of narrow zones. The first of these, the dentate gyrus (DG), is actually a separate structure, a tightly packed layer of small granule cells
Neuroanatomy of memory with Parkinson's disease would find this difficult. He or she would also have trouble encoding this visual and spatial information into long-term memory. This suggests that the basal ganglia work in both encoding and recalling spatial information. People with Parkinson's disease display working memory impairment during sequence tasks and tasks involving events in time. They also have difficulty in knowing how to use their memory, such as when to change strategies or maintain a train of thought. Neuroanatomy of memory The neuroanatomy of memory encompasses a wide variety of anatomical structures in the brain. The hippocampus is a structure in
