Functions of the Brain and Homunculus
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.
