title: [Initiation potential of the brain cortex before memory-guided saccades].
abstract: Longer latency and duration of memory-guided saccades and their lower amplitude compared with visually-guided saccades testify to the slower programming of the former. Lateral distinctions in the latencies and durations of memory-guided and visually-guided saccades can reflect leading role of the right hemisphere in programming memory-guided saccades and leading role of the left hemisphere in programming visually-guided saccades. Topography and spatiotemporal dynamics of presaccadic potentials P-1 and N-1 within the last 100 ms of latent period suggest that the mechanisms of final stage of the programming of memory-guided and visually-guided saccades are different. Shorter latencies of the presaccadic P-1 and N-1 prior to memory-guided saccades testify to acceleration of the initiation of the memory-guided saccades. The acceleration of the initiation period of memory-guided saccades suggest that deceleration of memory-guided saccade programming occurs at the stages preceding saccade initiation.
