What is the role of the hippocampus in memory?

What is the role of the hippocampus in memory?

The hippocampus is thought to be principally involved in storing long-term memories and in making those memories resistant to forgetting, though this is a matter of debate. It is also thought to play an important role in spatial processing and navigation.

What is the role of the hippocampus in the stress response?

The hippocampus is a key brain area involved in the regulation of the stress response, exerting negative feedback on the hypothalamic–pituitary–adrenal (HPA) axis (Jacobson and Sapolsky, 1991), the system within the body responsible for the release of glucocorticoid stress hormones.

What is the role of the hippocampus and amygdala in memory?

The amygdala is involved in fear and fear memories. The hippocampus is associated with declarative and episodic memory as well as recognition memory. The cerebellum plays a role in processing procedural memories, such as how to play the piano. The prefrontal cortex appears to be involved in remembering semantic tasks.

How does the hippocampus affect emotions?

The hippocampus, located in the medial temporal lobe and connected with the amygdala that controls emotional memory recalling and regulation (Schumacher et al., 2018); it has increased the functional connectivity with anterior cingulate or amygdala during emotional regulation and recalling of positive memory (Guzmán- …

Why is the hippocampus so vulnerable to stress?

The hippocampus may be especially prone to stress-induced functional and structural modifications due to its unique capacity for neurogenesis in the adult brain (22), its high concentrations of receptors for stress hormones (23), or both.

How does the hippocampus affect behavior?

The ability to learn new information about a person, or ourselves, that is tied to a specific event or experience is a characteristic feature of hippocampal-dependent memory, and contributes to our ability to form relationships with others, influences our behaviors towards others, and affects our judgments and …
