During the initial phases of the Wholly Drawing research, 
a study was done on the brain to identify distinct regions
that are activated during engagement in observational drawing.
The primary focus of this investigation was to determine the
origins of visual impressions and their corresponding neural
mappings in the brain. Additionally, the study aimed to identify
the mechanisms responsible for generating involuntary
motor actions by the body in response to (an observed) stimuli.
