Cortical Activity Changes after Art Making and Rote Motor Movement as Measured by EEG: A Preliminary Study by Juliet L King in BJSTR
Abstract
This preliminary quantitative EEG study explores the differences in
cortical activation patterns of subjects immediately following art
making and following rote motor tasks of coin tossing and pencil
rotation. It is hypothesized that a sustained, statistically significant
difference
from baseline occurs in cortical activity patterns, in respect to power
and frequency, after art making, and after the performance of non
creative
rote motor tasks, and that such differences can be detected and
quantified with the electroencephalogram (EEG). Ten consenting study
subjects
underwent EEG recording prior to, during, and after art making and rote
motor tasks. Baseline control recordings prior to either task showed
minimal changes in EEG power. In comparison, recording made immediately
following art making showed a consistent pattern of increased
power over the baseline EEG in specific frequencies over both
hemispheres, which persisted through the end of the 12 minutes that data
was collected. Recordings made immediately following performance of the
rote motor tasks also showed a consistent pattern of increased
power over the baseline EEG in specific frequencies over both
hemispheres. The increase in power seen after art making was greater
than the
increase in power seen after the rote motor tasks. These preliminary
findings suggest that EEG may be a meaningful tool for quantifying
cortical
activation in the study of creative arts. This study will be expanded to
include comparisons of the data during art-making and during motor
tasks. It points to further exploration of this methodology and the
expansion of more advanced techniques using Mobile Brain Body Imaging
(MoBI) in experimental designs. This technique may provide an easily
accessible method of quantitative measurement for evaluating aspects of
brain activity and function in the study of the neuro scientific basis
of creative arts, neuron aesthetics, and art therapy.
