The brain is divided into three regions: fore brain, mid brain and hind brain:

Fore brain: 

1. The fore brain includes the cerebrum and the olfactory lobes. 

2. The cerebrum is the largest part of the brain and consists of two cerebral hemispheres. It has sensory areas where information is received from sense organs, Similarly there are motor areas from where impulses are sent to effector organs. 

3. In the cerebrum specific regions for each kind of stimulus and its response are located. E.g., there are specialized regions for hearing, smell and sight. 

Mid brain: 

1. It is made up of thalamus and hypothalamus. 

2. It connects the fore brain to the hind brain. 

Hind brain:
