Exposure to an enriched environment increases brain size. This size increase is related to each of these EXCEPT:
A) the density of glial cells.
B) the density of dendritic spines.
C) the size of synapses.
D) decreases in the length of pyramidal-cell dendrites.

Question

Quizplus · Accepted Answer

Increases in brain size following exposure to an enriched environment are associated with increased densities of glial cells, dendritic spines, and synapses. However, decreases in the length of pyramidal-cell dendrites are not related to this increase in brain size.
