Describe functional areas of cerebral cortex.
✓
Answer
Functional areas of cerebrum:
- There are three functional areas in cerebrum viz., sensory, association and motor area.
- In sensory area, sensory receptors bring the sensory inputs. These inputs are analysed in sensory area.
- The sensory speech area is located in parietal lobe. It is called Wernicke’s area.
- Association area forms the major portion of the cerebrum. It processes, analyses and stores the information given by the inputs. Power of reasoning, will, understanding, memory, etc. are the faculties present in the cerebral cortex.
- Motor area is present in the frontal lobe lying anterior to the premotor area. In the lower part of the motor area just above the lateral sulcus lies the Broca’s area or motor speech area. The Broca’s area controls the movements necessary for speech.
