A set of brain structures located at the border of the cortex and responsible for a variety of functions. One of the chief responsibilities for the limbic system is survival and another is memory accessment and storage. Two of the major parts of the limbic system are the amygdala and the hippocampus. The amygdala decides where each memory should be stored in the brain and the hippocampus sends it there. The placement is said to be determined by the level of emotional response that it receives.
The limbic system is also responsible for hormone levels, body temperature and motor functions. The parts of the limbic system are the amygdala, the cingulate gyrus, the fornixm the hippocampus and the hypothalamus.
