In their article on the relationship between handedness and cerebral asymmetries of pars triangularis and planum temporale, Foundas et al1 summarize the findings of Levy and Reid2 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.
