Motory and Sensory Homunculus:

Represents face, limbs, trunk:

1. Motory: Precentral gyrus (principal motor area); area 4.

2. Sensory: Postcental gyrus (principal sensory area); area 3-1-2 (somesthetic area). Both reflect somatotropic representation (note size aportioned to each organ).

Important Functions of the Brain in General:

1. Sensory integration (from receptors, auditory and visual stimuli).

2. Information storage - memory.

3. Generation of thought processes, ambition.

4. Motor co-ordination.

5. Execution of human desires.

6. Vegetative integration via the autonomic nervous system.

7. Affect: firmness, benevolence, cautiousness, combativeness, love, self-esteem, music, friendship, acquisitive, time, locality, calculation, destructiveness, etc.

8. Dominance.
