The limbic system is the area of the brain that controls human behavior and emotions, especially when it comes to behaviors like eating, reproducing, and raising offspring as well as fight-or-flight reactions.
The hypothalamus, amygdala, thalamus, and hippocampus are the four major components of the limbic system.
The limbic system's components are buried deep inside the brain, above the brainstem, and below the cerebral cortex.
