Preview effects across saccades are stronger in early visual cortices during active vision than in steady-gaze control, as measured with MEG and eye-tracking in humans.
- Why it matters: It remains unclear whether fixation periods receive additional neural modulation beyond efference-copy and rhythmic saccade timing, leaving a gap in how active vision shapes early processing.
- What they did: Human participants completed a gaze-contingent trans-saccadic change task while MEG and eye-tracking were recorded, enabling comparison of cortical responses when objects entered focus versus during steady fixation.
- The result: Sequential cortical modulations across saccades in primary visual and ventral occipital cortices were increased under active vision, and the pattern cannot be explained by adaptation alone.
