Question

Quizplus · Accepted Answer

Synaptic pruning, where excess neurons and synaptic connections are eliminated, begins in early adulthood (and even earlier, during childhood) to improve the efficiency of neuronal transmissions. Brain development actually begins in the first trimester, not the second, and the number of connections in the brain typically does not increase through adulthood; rather, it's the strength and efficiency of connections that can improve with learning and experience.
