![The three principal cases recorded in this section are particularly important from a psychological point of view. They enable us to trace Will or Volition to its sources —when we find persons unable to Will an act in response to a Visual Impression, though they can at once and without hesitation effectively Will the same act in response to a related Auditory Impression—or vice versa (pp. 353, O ir'x O'OO). B. Aphasia. 5.—Damage to the first parts of the outgoing tracks leading from the Cerebral Word-Centres to the left Corpus Striatum. Hitherto we have been considering defects resulting from abnormal conditions of the Auditory and Visual Word-Centres themselves, or from injuries to their ‘ afferent ’ or ‘ commissural ’ fibres; now we turn to the illustration of the results following upon injuries to the ‘ outgoing ’ fibres from these and from the Kinsesthetic Word-Centres—those which bring them into relation with given, and affording also some information of the kind referred to. Of this patient it is said:—“ He could write very well from dictation, but shortly after he was unable to read the words he had written, and he suffered in general from complete alexia \i.e. inability to comprehend written symbols]. By means of a stratagem, however, as he himself very clearly explained, he suc- ceeded in reading the word he had written from dictation upon the tablet. He passed his finger over each letter of the written word as if he were writing it again and read it while so doing. He then made a sort of calculation and counted off the sum of the separate letters.” Here apparently the Kinmsthetic Impressions from Writing-movements were capable of rousing related parts of the Auditory Word-Centre so as to enable them to act through the other portion of the Kinsesthetic Word-Centre, and thus evoke Speech-movements.](https://iiif.wellcomecollection.org/image/b2805961x_0645.jp2/full/800%2C/0/default.jpg)
