Initiation of evasive manoeuvres during self-motion: a test of three hypotheses.

abstract：:The aim of the present study was to assess the effects of dopaminergic medication on the selection-for-action mechanisms in Parkinson's disease (PD). PD subjects were tested after not having taken medication for at least 12 h ("Off' state) and then retested 1-2 h after medication ("On" state). A three-dimensional kine...

abstract：:After several days of exposure to optically-imposed post-saccadic retinal slip, the saccades of normal monkeys acquire an exponential ocular drift. This drift is in the direction of the imposed image motion, and persists in the dark. It has been argued that these changes result from the operation of a visually mediate...
