00:49 number of brain receptors interacting
00:50 with dopamine is higher in adolescents
00:52 than at any other time of life that
00:55 means that when a teen is exposed to a
00:57 reward such as a compliment the reward
00:59 center reacts more strongly than it
01:01 would for an adult also being with
01:03 friends increases the sensitivity to
01:05 rewards and makes the already sensitive

01:51 prefrontal cortex is the area where
01:53 decision-making occurs drug use can
01:56 result in poor grades memory loss and
