During early adolescence, young people experience changes in the levels of various _________, which are the chemicals that transmit signals throughout the brain. a. hormones b. synapses c. neurotransmitters d. lymphatic transmitters 83. During early adolescence, there is a marked increase in the dopamine activity in the ______, which is the seat of rationality, and in the ______, which is the seat of emotions. a. prefrontal cortex; limbic system b. brainstem; cerebellum c. temporal lobe; parietal lobe d. reticular formation; pons 84. Under the influence of changing neurochemical levels, teenagers a. are increasingly drawn to novel situations. b. react more strongly to stressful situations. c. are more prone to negative emotional reactions. d. exhibit all of these. 85. In a study in which adults and adolescents were asked to label the emotion of a person in a photograph with their brains being imaged, the researchers found  a. that the adolescents correctly labeled the emotion 100 percent of the time. b. that the adults often saw a different emotion than the correct one. c. that the adults relied on the prefrontal cortex to identify the emotions. d. all of these. 86.
