Journal of Nervous and Mental Disease. CX, 1949: Mass Action versus Mosaic Function of the Frontal Lobe. Walter Freeman. Pp. 413–418.

From the study of lobotomized patients, Freeman concludes that motor skills seem to depend on the convexity of the frontal lobe while awareness of self and orientation seem to depend on the base. Recognizing that both motor skills and sensory functions are products of many factors which can be related to the development of the individual from infancy to maturity, Freeman discusses these two groups of functions as they are affected in lobotomized patients. He points out that '… simple movements known to be under the control of the frontal motor cortex are elaborated into mechanical skills, social, occupational, recreational and creative skills. Simple visceral sensations are elaborated into internal and external orientation, and on into social and spiritual self-consciousness, with creative ecstasy as the highest achievement of the functioning individual. Since this creative ecstasy is the only function apparently destroyed by transorbital lobotomy, it may safely be attributed to the most anterior portions of the frontal lobes.'
