Functional Brain Systems: Limbic System
2.2K
The limbic system, often called the "emotional brain," is a complex set of structures located deep within the brain. The intricate network of the limbic system supports a wide range of psychological functions, from emotional regulation to memory formation and sensory processing. This functional brain region encompasses specific parts of the diencephalon and the cerebrum, integrating the higher mental functions of the cerebral cortex with the primitive emotional responses of the deep...

Role of Amygdala in Memory
130
The amygdala is a small, almond-shaped structure responsible for processing and storing memories, particularly those linked to emotions like fear and stress. It plays an essential role in the brain's response to emotionally significant events and often enhances memory formation by triggering stress hormone release. The amygdala is vital for encoding and retrieving memories associated with fear or stress, a process that is adaptive by helping organisms avoid dangerous situations.
