In the letter to the editor entitled “Crossed Nonaphasia in a Dextral With Left Hemispheric Lesions: Handedness Technically Defined” by Derakhshan,1 2 sentences were inaccurate. Corrections are as follows:
Paragraph 3, sentence 3 should read as follows (corrected word in bold): Only electrodiagnostic methods have the temporal resolution necessary to discern which hemisphere controls the other through the callosum via an excitatory synapse (evidenced by occurrence of diaschisis symptomatology contralateral to the minor hemisphere on interruption of its excitatory connection from the major hemisphere, in the twin syndromes mentioned above).
Paragraph 4, sentence 4 should read as follows (corrected word in bold): The lack of left-hand apraxia and absence of aphasia in their subject indicated that the patient was neurally left-handed.
The author apologizes for these errors.
