Impulsiveness during adolescence is not unique to us, according to a study which suggests that the brains of human and other primates go through similar changes in teen years, particularly in the areas that affect self-control. “As is widely known, adolescence is a time of heightened impulsivity and sensation seeking, leading to questionable choices,” said Beatriz Luna of the University of Pittsburgh in the US. “However, this behavioral tendency is based on an adaptive neurobiological process that is crucial for molding the brain based on gaining new experiences,” Luna said.

Understanding the neural mechanisms that underlie this transitional period in our primate counterparts is critical to informing us about this period of brain and cognitive maturation, said Luna.
