The limbic lobe is a critical part of the brain that's responsible for a variety of functions related to emotion, learning, and memory. The limbic lobe includes several distinct structures like the hippocampus, amygdala, and cingulate gyrus. These structures are interconnected and work together to influence thought and behavior. Synonyms for the limbic lobe include the limbic system, the emotional brain, and the paleomammalian cortex. These terms are often used interchangeably and refer to the same group of structures. Understanding the limbic lobe and its functions can be helpful for treating a range of conditions, from anxiety and depression to Alzheimer's disease and addiction.
