The most likely explanation for the excess proliferation of neurons in early development is that it:
A) compensates for connection errors.
B) uses up excess stored fuel.
C) increases learning capacity when it is most needed.
D) prevents apoptosis.

Question

Quizplus · Accepted Answer

The excess proliferation of neurons in early development is most likely due to the fact that it compensates for connection errors. As the brain develops, neurons must make connections with one another in order to form functional circuits. However, because these connections are made through a process of trial and error, some connections will inevitably be incorrect. By producing an excess of neurons, the brain is able to compensate for these errors by creating redundant connections. Once the correct connections are established, the excess neurons will undergo apoptosis (programmed cell death), which helps to refine and optimize the neural circuits.
