[NEOLOGISMS AND MOTOR APHASIA. (Afferent pathology?)].

The authors describe a case of post-traumatic aphasia in a 39-year-old man. The linguistic disturbances were marked by the unusual association of oral expression consisting mainly of neologisms, normal comprehension and almost normal written expression. A physiological interpretation based on disturbance of treatment of the sensory afferent nerves from the bucco-phonator organs is suggested to account for the neologisms in this particular form of aphasia.
