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 children grow up in agreeable circumstances, however an unfortunate 8.1% are raised in households that fall into the category of low socioeconomic status. These children are at risk for many disadvantages in life, including deficits in memory processing, as well as problems in language development. Working memory is a temporary storage system that is essential for the successful performance of the task at hand. When creating new memories, the hippocampus and related structures of the brain play a key role in consolidation. Memory consolidation is the transformation of short-term memories to long-term memories, which is crucial in the acquisition of
