| Abstract: | Abstract We report the case of a patient, ML, who experienced persistent inner speech vocalizations following bilateral brain injury. The vocalizations consisted of fragments of hymns or prayers learned in childhood; also, repetitions of recent thoughts or heard speech. These were not of a schizophrenic type: they were in her own voice, did not ‘speak to her’ or give orders, and were clearly acknowledged to be internal in origin. We offer a tentative explanation in terms of the excitation of a right hemisphere store of early-acquired, overlearned material combined with the dysfunctioning of a left hemisphere working memory system. |
