The hippocampus is a region of the brain that plays a critical role in memory and spatial navigation. Research on hippocampal function aims to understand how this structure processes and stores memories, as well as how it contributes to learning and cognitive processes. Studies in this area often involve tasks such as learning and memory tests, neuroimaging techniques, and animal models to investigate the neural mechanisms underlying hippocampal function. Researchers also explore how dysfunction in the hippocampus can lead to cognitive impairments seen in conditions such as Alzheimer's disease and other neurological disorders. Overall, research on hippocampal function provides valuable insights into the workings of the brain and how memories are formed and retrieved.
