Summary Introduction

Introduction:

The brain is a complex system that controls various activities. The limbic system is a set of brain structures that are present beneath the thalamus. The limbic system is involved in emotion, memory, learning, and motivation. Amygdala is an almond-shaped mass of nuclei located near the base of the cerebrum. It controls the emotional memory such as a frightening event that can trigger faster heart rate, sweating or fear. The medulla oblongata is the lower part of the brain stem. It deals with the autonomic functions, homeostatic functions such as breathing, heart rate, and blood pressure. The cerebellum is a part of the hindbrain. It controls involuntary activities such as blood circulation and coordinates motor activities such as locomotion.
