Answer: Subventricular zone (SVZ) and subgranular zone of hippocampal dentate gyrus.
- A All regions of the adult brain equally, with little regional specificity
- B Subventricular zone (SVZ) and subgranular zone of hippocampal dentate gyrus
- C Mainly within the granule cell layer of the cerebellum
- D Mainly within nuclei located in the brainstem
Correct answer: B. Subventricular zone (SVZ) and subgranular zone of hippocampal dentate gyrus
Explanation: Adult neurogenesis: new neurons continuously produced from neural stem cells in SVZ (migrating to olfactory bulb) and SGZ of hippocampal dentate gyrus. Functional significance in learning and memory.
