Morphologic cerebral asymmetries and handedness.

Abstract

In their article on the relationship between handedness and cerebral asymmetries of pars triangularis and planum temporale, Foundas et al 1 summarize the findings of Levy and Reid 2 as follows (italics are mine): They found that right-handed subjects with a noninverted writing posture and left-handed subjects who did not invert had a right visual field (left hemisphere) advantage on a verbal task, whereas right-handed subjects who did have an inverted writing posture and left-handed subjects who did not had a left visual field advantage (right hemisphere). I am one of the left-handed complement who has tried to understand his cerebral anomalies, 3 but after struggling unsuccessfully with that sentence, I now feel as if I have wandered from the planum temporale onto Matthew Arnold's darkling plain and joined the armies of the ignorant.
