Question

Quizplus · Accepted Answer

Gray matter in the brain is associated with processing and cognition, and studies have shown a correlation between the volume of gray matter in certain areas, such as the frontal cortex, and cognitive abilities like IQ. Gray matter primarily consists of neuronal cell bodies, dendrites, and unmyelinated axons, not myelinated axons as stated in option C. The volume of gray matter typically decreases after puberty, contrary to what is stated in option A, due to synaptic pruning. The statement in option D about the specific peak ages for gray matter volume in the caudate for boys and girls is not universally agreed upon and is too specific without broader context.
