background image BIO 264: Anatomy & Physiology I  MODULE NOTES: THE BRAIN  The brain is the center of the nervous system  Its functions include receiving, evaluating and responding to sensory input, 
storing information, planning future activities, reasoning and abstract thought. 
Functions are carried about by neurons, over 100 billion, which  use action  potentials  as a means of communicating to other parts of the brain or to the rest  of body.  Brain is divided into:  
The 
cerebrum  – largest and most superior part of the brain.  This is divided into two hemispheres by the longitudinal fissure and  each  hemisphere is further divided into lobes , making the frontalparietaltemporal  and the occipital lobes.  Cerebrum also consist of the cerebral cortex. 
Functions of the cerebral cortex includes memory, attention, perception, thought, 
movement, language and consciousness (it allows us to be aware of ourselves, to 
remember names, to communicate to others and to move voluntarily). 
The  diencephalon  (interbrain) – region at the core of the brain; surrounded by  the cerebral hemispheres. 
Diencephalon is the connection between the brain stem and the cerebrum and 
consists of three gray matter structures; the thalamusthe hypothalamus and 
the epithalamus
The thalamus edits and sorts out information and then categorizes similar 
functions to be relayed as a group to the appropriate areas of the cerebral cortex. 
The hypothalamus is the visceral control center, it regulates functions of the 
internal organs. It is chiefly concerned with maintaining homeostasis. It is 
sometimes referred to as the brain within the brain
The epithalamus is the most dorsal of the structures of the diencephalon.
