Research on the brain development of mice that are raised in environments offering different degrees of stimulation suggests that the increased intelligence seen in children raised in more stimulating environments is due to
A)activation of genes involved in forming new neurotransmitters.
B)increases in the kinds of neurons formed.
C)increases in the number of new neurons formed.
D)increases in the number of synaptic connections.

Question

Quizplus · Accepted Answer

Research on the brain development of mice has shown that an increased number of synaptic connections is a key factor in the increased intelligence observed in mice raised in more stimulating environments. This suggests that a similar mechanism may underlie the increased intelligence seen in children raised in more stimulating environments.
