文摘
- •
Brain signals were measured during a covert visual spatial attention task.
- •
Groups of young and elderly subjects performed the task equally well.
- •
Stimulus-locked event-related potentials were similar for both age groups.
- •
Alpha power and alpha lateralization were strongly reduced in elderly subjects.
- •
These electrophysiological changes were consistent on the single-trial level.
