- Hippocampus Functions. By Dr Ananya Mandal, MD. The hippocampus is a small organ located within the brain's medial temporal lobe and forms an important part of the limbic system, the region that regulates emotions.The hippocampus is associated mainly with memory, in particular long-term memory.xperts generally agree that the hippocampus plays a role in the formation of new memories and in the detection of new surroundings, occurrences and stimuli. Some also believe the organ is involved in declarative memory; that is memories that can be stated verbally such as facts and figures.

What Is the Role Of the Hippocampus? Because the hippocampus plays such an important role in the formation of new memories, damage to this part of the brain can have a serious long-term impact on certain types of memory. Damage to the hippocampus has been observed upon post-mortem analysis of the brains of individuals with amnesia.

Hippocampus In Alzheimer's disease, the hippocampus is one of the first regions of the brain to suffer damage; memory loss and disorientation are included among the early symptoms. Damage to the hippocampus can also result from oxygen starvation (hypoxia), encephalitis, or medial temporal lobe epilepsy.amage to the hippocampus does not affect some types of memory, such as the ability to learn new skills (playing a musical instrument or solving certain types of puzzles, for example). This fact suggests that such abilities depend on different types of memory (procedural memory) and different brain regions.

- Though the hippocampus is an essential brain structure for the proper functioning of long-term memory, it cannot be regarded as the “memory centre” in the same sense that the occipital cortex, for example, can be regarded as the centre for processing visual information.he hippocampus is a very old part of the cortex, evolutionarily, and is located in the inner fold of the temporal lobe. All of the pieces of information decoded in the various sensory areas of the cortex converge in the hippocampus, which then sends them back where they came from.

What You Should Know About the Effect of PTSD on the Brain What is the Hippocampus? The hippocampus is a part of the limbic system of the brain. The limbic system describes a group of brain structures that surround the brain stem. The brain structures that make up the limbic system play a major role in experiencing certain emotions (fear and anger), motivations and memory. The hippocampus is responsible for the ability to store and retrieve memories.

- The reason is that long-term memory is not located in just one specific area of the brain. The hippocampus is the catalyst for long-term memory, but the actual memory traces are encoded at various places in the cortex. The destruction of both hippocampi (as the result of a stroke, for example) has disastrous effects on long-term memory, preventing the individual from learning anything new whatsoever. The most important evidence of the role of the hippocampus in transferring long-term memories has been provided by subjects who had sustained damage to both hippocampi and could not keep things in their memories for more than a few moments.

Hippocampus: Definition, Function & Location The Hippocampus and Memory. The hippocampus plays a very important role in our memories. The hippocampus attaches memories to the emotions and senses that went with them. For instance, it will take a memory of being happy and calm while in a field and link it with the smell of the flowers.he limbic system is the area in the brain that is associated with memory, emotions, and motivation. The limbic system is located just above the brain stem and below the cortex. The hippocampus itself is highly involved with our memories.

Hippocampus The hippocampus, Latin for seahorse, is named for its shape. It is part of a system that directs many bodily functions: the limbic system. This system is located in the brain's medial temporal lobe, near the center of the brain. The hippocampus is involved in the storage of long-term memory, which includes all past knowledge and experiences. Scientists are unsure exactly how this occurs.

Hippocampus People with extensive, bilateral hippocampal damage may experience anterograde amnesia—the inability to form and retain new memories. In rodents, the hippocampus has been studied extensively as part of a brain system responsible for spatial memory and navigation. Many neurons in the rat and mouse hippocampus respond as place cells: that is, they fire bursts of action potentials when the animal passes through a specific part of its environment.

- Related areas. Besides the hypothalamus, hippocampus, and amygdala, there are other areas in the structures near to the limbic system that are intimately connected to it: The cingulate gyrus is the part of the cerebrum that lies closest to the limbic system, just above the corpus collosum. It provides a pathway from the thalamus to the hippocampus, seems to be responsible for focusing attention on emotionally significant events, and for associating memories to smells and to pain.
