Abstract
The effects of handedness and of familial left-handedness on the asymm etry of the cerebral hemispheres were investigated by means of visual evoked potentials. Square gratings of different spatial frequencies we re presented, at 1 Hz in ON-OFF mode to 60 subjects: 30 right-handers and 30 left-handers, 15 with familial handedness and 15 without in eac h group. The results show that the patterns of hemispheric asymmetry d iffer in right- and left-handers. They also show that in left-handers these patterns depend on the presence or absence of familial left-hand edness, whereas in right-handers the sole of this genetic factor is le ss evident.
