What are the functions of a brain ?
The brain is the most complex organ in the body. It is the organ that allows us to think, have emotions, move, and even dream.The brain and spinal cord make up the central nervous system and all of the nerves found in our body make up the peripheral nervous system.The wrinkles are called cortex and it is where the majority of brain cells or neurons reside. The cortex can be divided into four main lobes. The frontal lobe, where you do your heavy thinking, pondering and planning your actions; temporal cortex, where you process sounds and form memories; occipital cortex, where you process all the things that you see; and parietal cortex, where you integrate or makes sense of all of the different bits of information that are bombarding your brain.
 The Medulla Oblongata
Helps control the body's autonomic functions (things you don't need to think about to perform) like respiration, digestion and heart rate. Also acts as a relay station for nerve signals going to/from the brain.
The Pons
Has roles in your level of arousal or conciousness and sleep. Relays sensory information to/from the brain. Also involved in controlling autonomic body functions.
The Cerebellum
Mostly deals with movement. It regulates and coordinates movement, posture and balance. Also involved in learning movement.
