1646Sir T. Browne Pseud. Ep. iv. v. 187 This prevalency is uncertainly placed in the laterallity, or custom determines its indifferency.

They state that the direction and extent of deformation varied simply with the laterality of the lesion; deviations in right-sided cases were in an anti-clockwise direction..; in cases with left-sided lesions, they were in the opposite direction. 1964Dissertation Abstr. XXIV. 3423/2 Predictions of laterality of cerebral hemisphere lesions can be made with a fairly high degree of confidence for those patients with well-lateralized, rapidly expanding lesions. 1964M. Critchley Developmental Dyslexia viii. 51 Mixed laterality was then imagined to be a factor of special importance in dyslexics who might, for example, prove to be left-eyed, right-handed and left-footed. 1967Biol.
