Book excerpt: Excerpt from The Journal of Nervous and Mental Disease, Vol. 55: An American Journal of Neurology and Psychiatry; January-June, 1922 The division of sensibility in the peripheral nerves made by Head and Sherrin (i) into three forms, viz., epicritic, protopathic, and deep, has been attacked from many quarters. The onslaughts for the most part have centered on that form of dissociated sensibility in which the epicritic elements are suppressed, the protopathic ele ments being retained with their well-known characteristics, viz.: sud den entry into consciousness, poor localization, wide radiation, over reaction, and inability to name the stimulus. In the regeneration period after nerve section and suture Rivers and Head (2) found that this type of dissociation occurred as the result of the unequal rate of regeneration in' two separate sets of systems, the one mediating the protopathic elements recovering function somewhat in advance of the set which mediates the epi critic elements.
