D) Far more neurons are produced than will ultimately survive.

Question

Quizplus · Accepted Answer

Far more neurons are produced during embryonic development than will ultimately survive, with many dying off through a process called apoptosis. Neurons begin to form early in embryonic development and continue to develop after birth, but synapses (connections between neurons) are formed after birth through a process called synaptogenesis. Additionally, not all synapses that are formed are permanent, as some are eliminated through a process called synaptic pruning.
