Someone: Umm what…?
Me: I have summer brain right now:)

teen brain

Teen brains are the kind of brain that you once had during the onset of puberty until as late as your 20th birthday. This kind of brain makes the newly sexually active teen seek emotionally charged activities, thus increasing risk-taking behavior. Furthermore, MRI devices has also revealed that while the adults were using their prefrontal cortex to understand the expressions, teens were using their amygdala. The amygdala is responsible for inducing emotions and impulses, not logic and rational reasoning. In conclusion, while it is true that the size of our brains doesn’t change much beyond our 6th birthday, its under-the-hood workings are not done developing until the age of 25.

During my teen years, my brain was all about impulse and emotion; I often made decisions based on how I felt instead of thinking them through—classic teen brain behavior!
