See also Dr J. W. Russell, p. 113, The Medical Chronicle, May 1908. CENTRE OF SPEECH 201 interrupts tlie process of ideation and thought, such as sudden shocks of emotion or the like, will also cause inability to speak. Such states cannot properly be classed under the head of aphasia, where we have a definite condition of loss of speech, while all the other faculties — sensation, emotion, thought, and volition — remain practically unimpaired " (" The Functions of the Brain," by Dr D. Terrier, s...econd edition, 1886, p. 445). The term aphasia signifies "speechlessness," which may be divided into, first, speechlessness arising from the want of power from defect of memory to recall words previously learnt ; or else from the destruction of those parts of the cerebral cortex or centres for hearing, on which the impressions made by word sounds had been registered (Amnesia) ; and secondly, motor aphasia in which the loss of speech depends on a lesion of the nervous matter which constitutes Broca's centre of speech, or in its conducting fibres, passing through the basal ganglia to the nuclei of the nerves which control the action of the muscles of the vocal apparatus.
