When Researchers Use Brain-Imaging Technology to Investigate Patterns of Adolescent

When researchers use brain-imaging technology to investigate patterns of adolescent brain activation, what do they find?

A) Researchers find that regions of the brain that are especially sensitive to rewards are more intensely activated during early and middle adolescence than adulthood.
B) Researchers find that regions of the brain that are especially sensitive to rewards are less activated during early and middle adolescence than adulthood.
C) Researchers find that regions of the brain that are sensitive to punishment are more intensely activated during early and middle adolescence than adulthood.
D) Researchers find that regions of the brain that block the ability to perceive rewards are more intensely activated during early and middle adolescence than adulthood.
