Question

in the context of the human brains plasticity, research has found which of the following brain regions to be responsible for neurogenesis?

• amygdala
• medulla
• cerebellum
• hippocampus

Explanation:

To solve this, we analyze each brain region:

• Amygdala: Involved in emotion (fear, anxiety), not neurogenesis.
• Medulla: Regulates vital functions (breathing, heart rate), no neurogenesis role.
• Cerebellum: Controls movement, balance, not neurogenesis.
• Hippocampus: Research shows it's key for neurogenesis (new neuron formation) in adult brains, linked to learning/memory and brain plasticity.

Answer:

D. Hippocampus
