Which part of the brain is responsible for memory and emotions?
The hippocampus is a small, curved formation in the brain that is part of the limbic system, which is involved in emotion regulation and long-term memory formation.
1. It is located in the medial temporal lobe of the brain, beneath the cortical surface.
2. The hippocampus is crucial for converting short-term memories into long-term memories, a process known as memory consolidation.
It is also involved in spatial memory, which helps with navigation.
3. It works closely with the amygdala, another part of the limbic system, to process and retrieve emotional memories.
The hippocampus can influence how we perceive and respond to emotional stimuli.
4. Unlike many other brain regions, the hippocampus has the ability to generate new neurons throughout life, a process known as neurogenesis.
This is thought to play a role in learning and memory.
5. Chronic stress can negatively affect the hippocampus, potentially leading to memory problems and emotional disturbances.
High levels of stress hormones, like cortisol, can reduce the size of the hippocampus and impair its functions.
