title: Spatial disorientation in the monkey.
abstract: The incidence of misdirected movements of the hand during tactile discrimination performance in the dark has been tabulated for monkeys with bilateral removals of parieto-prestriate cortex. The observations support the existence of a spatial disorientation (in addition to their inaccuracies of reaching) in these animals.
