Studies of the infant brain show signs of what scientists call synaptic pruning. What occurs during this process?
A) The brain creates additional neural connections by removing parts of the surrounding bone.
B) Unused synaptic connections and nerve cells are cleared out to make way for new cells.
C) New cells work to "rewrite" old cells and ultimately change their functioning.
D) New cells will not develop until the body makes sufficient physical space within the brain.

Question

Quizplus · Accepted Answer

During synaptic pruning, unused or weaker synaptic connections and nerve cells are eliminated to make space for stronger and more frequently used connections, which helps to shape the developing brain. This process is important for optimizing brain function and is one reason why early childhood experiences and environments can have a significant impact on lifelong development.
