10.1152/jn.00141.2003. A vertical asymmetry in memory-guided sac-
cadic eye movements has been previously demonstrated in humans
and in rhesus monkeys. In the upright orientation, saccades generally
land several degrees above the target. The origin of this asymmetry
has remained unknown. In this study, we investigated whether the
asymmetry in memory saccades is dependent on body orientation in
space. Thus animals performed memory saccades in four different
