Evolution of Creativity
One of the distinctive abilities of human kind is creativity. But many species have survived without it. A new study done by Drexe’s College of Arts and Sciences has shown that creative insights or ‘aha moments’ trigger a burst of activity in the brain’s reward system-- the same system which responds to delicious foods, addictive substances, orgasms and other basic pleasures. This reward system of the brain motivates the behaviours that produce it. Therefore, individuals who experience insight-related neural rewards are likely to engage in further creativity-related activities potentially to the exclusion of other activities-- a notion that many puzzle aficionados, mystery-novel devotees, starving artists and underpaid researchers may find familiar. The researchers tested the EEG recordings of people involved in solving anagram puzzles and given questionnaire to test their ‘reward sensitivity.’ Reward sensitive people showed an additional burst of high frequency gamma waves orginating after the ‘gamma-band’ brainwaves in the orbitofrontal cortex of the brain.
