fMRI shows unique brain regions are increasingly devoted to social self-evaluations during puberty A specific region of the brain is in play when children consider their identity and social status as they transition into adolescence -- that often-turbulent time of reaching puberty and entering middle school, says a University of Oregon psychologist. In a study of 27 neurologically typical children who underwent functional magnetic resonance imaging (fMRI) at ages 10 and 13, activity in...

(Ivanhoe Newswire) "“ Adolescence is usually characterized as a tumultuous time. Previous research has pointed to the immature brain as a major cause, but now, this unique study reveals that some brain changes associated with adolescence may not be driving teens towards risky behavior but may actually reflect a decrease in susceptibility to peer pressure. Subcortical neural systems associated with emotional responses are believed to mature earlier than the higher cortical areas that...

Scans with fMRI show areas in brain that change in response to emotions as children enter adolescence Just when children are faced with intensifying peer pressure to misbehave, regions of the brain are actually blossoming in a way that heighten the ability to resist risky behavior, report researchers at three West Coast institutions. The findings -- detailed in the March 10 issue of the journal Neuron -- may give parents a sigh of relief regarding their kids as they enter adolescence and pay...

Adolescence is often described as a tumultuous time, where heightened reactivity and impulsivity lead to negative behaviors like substance abuse and unsafe sexual activity. Previous research has pointed to the immature adolescent brain as a major liability, but now, a unique study reveals that some brain changes associated with adolescence may not be driving teens towards risky behavior but may actually reflect a decrease in susceptibility to peer pressure. The findings, published by Cell...

Functional magnetic resonance imaging confirms the influences of peer, parents on self identityAsk middle-school students if they are popular or make friends easily, they likely will depend on social comparisons with their peers for an answer. Such reliance on the perceived opinions of others, or reflected self-appraisals, has long been assumed, but new evidence supporting this claim has now been found in the teen brain.Using functional magnetic resonance imaging (fMRI), researchers looked at...
