Gehirnscans von 5.832 Jugendlichen (8–11 Jahre) ergaben, dass stärkere Amygdala-Reaktionen auf emotionale Gesichter zwei Jahre später unterschiedliche soziale Ergebnisse vorhersagten: Eine erhöhte Amygdala-Aktivität bei Mädchen sagte eine stärkere Beteiligung an Gleichaltrigen voraus, bei Jungen jedoch eine geringere Beteiligung

>The “social brain” is an idea from neuroscience that specific key brain regions are behind nearly every aspect of our social behavior. These brain regions help us recognize people we know, and they guide us in understanding the thoughts of others as well as our own. These regions’ development during adolescence plays an important role in peer relationships later on, but it’s been unclear exactly how.

>This study tested the social brain’s impact on future social health with data from 5,832 participants in the Adolescent Brain Cognitive Development, or ABCD, Study. Participants were between 8 and 11 years old between 2017 and 2018 when shown images of either faces or places while their brain activity was observed with fMRI imaging showing blood flow in the brain. Data on their social health was collected two years later.
>
>The team compared brain activity when participants viewed faces, which contain a high amount of social information, versus places, which have none. They also compared brain activity when participants viewed faces showing positive or negative emotions and faces showing no emotion. 
>
>In addition to finding that high amygdala activation predicted boys and girls moving in opposite directions socially two years later, the analysis showed that the amygdala was the only brain region that predicted a participant’s future social health.

Therefore, the amygdala is the “boys are icky” part of the brain.
