Human observers who lack stereopsis reliably make eye-of-origin discriminations for grating patterns under conditions that render the performance of normal observers unreliable. This lends support to the view that stereoblind individuals possess proportions of monocular and binocular cortical cells similar to those of cats and monkeys deprived of early binocular visual experience.
