Excitatory and projective functions
- The hippocampus is comprised primarily of pyramidal cells, which are multipolar neurons that have excitatory and projective functions. This structure is also divided into different regions called fields named CA1, CA2, CA3, and CA4. The hippocampus receives input and sends output to the rest of the brain via the entorhinal cortex.

Alzheimer’s disease may affectTrusted Source the area of the hippocampus first. Early signs of Alzheimer’s disease become noticeable when the person begins to lose their short-term memory. They may also find it difficult to follow directions. As the disease progresses, the hippocampus loses volume, and it becomes harder to function in daily life.
Changes to the hippocampus are also associated with epilepsy. ResearchTrusted Source has found a connection between epilepsy and a difference in how the hippocampus makes new neurons. However, it is not clear whether these differences happen before or after the onset of epilepsy.
In people with severe depression, the hippocampus hasless volume. Scientists are unsure whether the small size results from depression or if it is a contributing factor. Evidence suggests that stress may causeTrusted Sourcea negative impact on the hippocampus.
Function. What does the hippocampus do? Your hippocampus is responsible for the following cognitive functions: Learning. Short- and long-term memory. Visual-spatial memory (remembering the position of your body in relation to nearby objects). Verbal memory (remembering the right words to say).
Sep 19, 2023 · Anatomy. Function. Damage. Research Studies. In psychology, the hippocampus is a crucial structure within the brain’s medial temporal lobe. It plays a vital role in forming and retrieving memories, spatial navigation, and emotional responses.
May 14, 2024 · The hippocampus is a region of the brain that is associated primarily with memory. The hippocampus is thought to be principally involved in storing long-term memories and in making those memories resistant to forgetting. It is also thought to play an important role in spatial processing and navigation.
Aug 12, 2022 · Modified: 12 Aug 2022. What is the hippocampus? The hippocampus is a small but complex brain structure that plays an important role in the process of learning and the formation of new memories. The word hippocampus comes from the Greek words “hippo”, meaning horse, and “kampos”, meaning sea monster.
