The adolescent brain is sensitive to environmental influences
• Experience influences what connections are kept and strengthened.
• Trade-off in adolescence: losing unused connections for increased efficiency.

“When people expect to have future access to information, they have lower rates of recall of the information itself and enhanced recall instead for where to access it.” (Sparrow et al., 2011)
