This study presents a modified, single subject design that measured the patterns of electrical activity of a participant's brain following an hour spent painting and drawing. Paired t tests were used to compare pre and post art-making electroencephalograph (EEG) data. The results indicated that neurobiological activity after drawing and painting was statistically different (p < .05) from activity measured at a state of rest. In general, the higher frequency bands (alpha and beta) were
