SOC 316 Lecture Notes - Lecture 1: Prefrontal Cortex, Grey Matter, Functional Magnetic Resonance Imaging
Document Summary
Use brain imaging to understand the adolescent brain. Snapchat high resolution of the inside of the brain calculating grey matter and how much the brain contains with age. Reveals the brain continues to develop in the 20-30. Adolescence : period of life that starts with biological hormonal physical changes or puberty ends stage when individuals reaches stability in society. Prefrontal cortex: decision making planning inhibiting inappropriate behavior social activities. Grey matter contains cell bodies and connection of cell (syntax) Grey matter volume 4-22 increases in childhood pearks through early adolescence. Peaks more so in boys than girls because of puberty. Grey matter depends on the environment the synapses that are used stay and the ones that aren"t fade away. Mid prefrontal cortex: more active in adolescents. Declines in adults because adults and children use different mental approaches to make social decisions. In limbic system: emotion regarding reward and risk taking higher in adolescents than adults.
