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) more synaptic connections

Question

Quizplus · Accepted Answer

Research suggests that increased intelligence seen in children raised in more stimulating environments is due to the development of more synaptic connections in the brain. This is supported by studies on mice raised in different environments, which have shown that the number of synapses in the brain is directly related to the degree of environmental stimulation. Therefore, option D, more synaptic connections, is the best choice.
