Question

Quizplus · Accepted Answer

Neurogenesis is not uniform throughout the brain. Different regions of the brain have varying rates of neurogenesis.

Answer: D 
 The majority of neurons are in place by 10 weeks after conception in humans. After this point, the brain primarily undergoes synaptic pruning and myelination. BDNF actually promotes neurogenesis, so option A is false. Option C is also false, as neurogenesis can occur throughout life.
