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
Socioeconomic status and memory the time. As people recall a former memory, the door to memory reconsolidation is opened. Reconsolidation refers to the retrieval of a memory from long-term storage to short-term working memory, where it is unstable and vulnerable to alteration. As reported by Staff et al. (2012), socioeconomic status measured early in childhood reared a significant difference in hippocampal size in adulthood, suggesting that there is in fact an impact on brain and cognitive development. Spatial memory is another specialized function of the brain, and more specifically, the hippocampus. Spatial memory refers to experiences that are recognized by their surrounding environment. Many
