A Case for Neuroaesthetics: How Our Brain Perceives Aesthetic Experiences By Annie Chen, Biochemistry, 2021

esthetic experiences permeate our daily lives by enriching our experiences and thereby creating a more fulfilling life. Some of us choose to paint, some choose to dance, while others choose to listen to music. The interesting question of how our brain perceives and judges art and aesthetic experiences paved the way for “neuroaesthetics”: the intersectional study of the brain and art.3 Although aesthetic objects themselves do not directly confer value for survival, they are an essential part of human culture.4 Art is an evolutionary imperative. Through the reward, pleasure, and fear circuitry in the Photo courtesy of M.
