Question

neurons located in the ______ and in the olfactory cortex continue to appear and grow as the adult brain ages.
○ thalamus
○ hippocampus
○ amygdala
○ basal ganglia

Explanation:

In adult brain aging, neurogenesis (new neuron formation and growth) is known to occur in the hippocampus (involved in memory and learning) and the olfactory cortex. The thalamus is a relay center, amygdala for emotion, and basal ganglia for motor control; they don't have the same adult neurogenesis as the hippocampus here.

Answer:

B. hippocampus
