Broadly defined, positive neuroscience is the study of what the brain does well. Instead of studying mental illness, positive neuroscientists focus on valued cognitive qualities that serve to enrich personal life and/or society. Topics in positive neuroscience overlap heavily with those of positive psychology, but use neuroimaging techniques to extend beyond the behavioral level and explain the neurobiology which underpins "positive" cognitive phenomena such as intelligence, creativity, optimism, and healthy aging.
