Phrenological studies of aphasia before Broca: Broca's aphasia or Gall's aphasia?

Abstract

The history of aphasia is usually taken to begin with Broca's (1861a,b) discovery of the correlation of aphemia with damage to the posterior inferior portion of the frontal lobes and the subsequent relation to left hemisphere. That there were prior, even biblical, references to aphasia is not in dispute, nor that, according to Benton and Joynt (1960), almost all the clinical forms of aphasia had been described prior to 1800. The significance of Broca's case studies, therefore, lies in the association of motor aphasia with focal pathology in the frontal lobe. This paper examines the status of aphasia localization prior to Broca, and, specifically, the extent to which Broca's discovery may have been anticipated by the phrenologists.
