Fore-brain
The main thinking part of the brain.
Feeling full
After a good meal, Asha says, I cannot eat any more, I feel full. Nobody told her this from outside.

What this lesson covers
The idea
The fore-brain is the main thinking part: separate areas receive sensory impulses, association areas interpret them with stored information, motor areas control voluntary muscles, and a separate centre is associated with hunger.

Receive, interpret, act
The fore-brain first receives the information, then interprets it, then passes the decision on to the muscles. A separate centre tells us when we have eaten enough.
The fore-brain is the main thinking part of the brain. Sensory areas receive impulses from receptors, association areas interpret them with stored information, and motor areas control voluntary muscles. A separate centre associated with hunger gives the feeling of being full.

Which areas of the fore-brain receive sensory impulses from receptors?
What do association areas put the sensory information together with?
Which areas control the movement of voluntary muscles such as the leg muscles?
The feeling of being full comes from which place?
- Motor areas. Motor areas control the movement of voluntary muscles.
- Sensory areas, which are specialised for hearing, smell, sight and so on — correct. Yes!
- Association areas. Association areas interpret information that has already been received.
- Information from one receptor only. Association areas also use information from other receptors and information already stored.
- Hormones from the blood. The book says association areas use information from other receptors and information already stored in the brain.
- Information from other receptors and information already stored in the brain — correct. Yes!
- Motor areas — correct. Yes!
- Sensory areas. Sensory areas receive impulses from receptors.
- Association areas. Association areas interpret the information and the decision is passed on to the motor areas.
- The motor areas of the fore-brain. Motor areas control voluntary muscles.
- A centre associated with hunger, in a separate part of the fore-brain — correct. Yes!
- The spinal cord. The feeling of being full is because of a centre associated with hunger in the fore-brain.
