Match List I with List II and select the correct answer using the codes given below : Codes : (a) (b) (c) (d)List I (Brain area) List II (Function) (a) Broca area (1) Non-reflexive movement (b) Wernicke area (2) Speech production (c) PFC (3) Planning and organization (d) Primary motor cortex (4) Speech comprehension
(2) (4) (3) (1)
Each brain area in List I has a well-established function:
| List I (Brain area) | List II (Function) | Reason |
|---|---|---|
| (a) Broca area | (2) Speech production | Left inferior frontal gyrus; damage (Broca's aphasia) gives slow, effortful, non-fluent speech with comprehension largely spared. |
| (b) Wernicke area | (4) Speech comprehension | Left posterior superior temporal gyrus; damage gives fluent but meaningless speech with poor comprehension. |
| (c) PFC | (3) Planning and organization | The prefrontal cortex supports executive functions: planning, organizing, working memory and inhibition. |
| (d) Primary motor cortex | (1) Non-reflexive movement | The precentral gyrus initiates voluntary (non-reflexive) movements, organized as a motor homunculus. |
The matching is therefore a-2, b-4, c-3, d-1.
Hence, the answer is (2) (4) (3) (1).
