Mustari and colleagues have shown that nasotemporal optokinetic nystagmus (OKN
) asymmetry and latent nystagmus (LN) in monkeys reared with binocular deprivation are due to defects in nucleus of optic tract (NOT).

Optokinetic reflexes have been measured by comparing the gain of optokinetic nystagmus (OKN

For research purposes, laboratory techniques such as visual evoked potentials (VEPs), electroretinograms, and optokinetic nystagmus (OKN
) can, and have, been used to study visual development.
