<P> Dr. Wilder Penfield and his co-investigators Edwin Boldrey and Theodore Rasmussen are considered to be the originators of the sensory and motor homunculi . They were not the first scientists to attempt to objectify human brain function by means of a homunculus . However , they were the first to differentiate between sensory and motor function and to map the two across the brain separately , resulting in two different homunculi . In addition , their drawings and later drawings derived from theirs became perhaps the most famous conceptual maps in modern neuroscience because they compellingly illustrated the data at a single glance . </P>
