Description
Saccades introduce frequent changes in visual input. Yet, visual perception seems introspectively continuous. How does perceptual continuity arise? Here, we examined the hypothesis that retinotopic representations (RR) are updated predictively presaccadically, with time-resolved MEG classification. A grating was presented at the same spatiotopic location across a saccade. We decoded spatial frequency and observed reliable decoding between 50 ms and 200-400 ms after stimulus onset and after saccade offset: the current RR. If these RR are updated presaccadically, then a post-saccadic classifier – trained with separate data, obtained while subjects fixated the post-saccadic fixation point – should be able to decode spatial frequency above chance before saccade onset: the future RR. Thus far, we only observed marginally above chance decoding of the future RR. Combined with reliable current RR decoding, this indicates that feedforward processing is stronger than spatiotopic updating.| Period | 26 Aug 2018 → 30 Aug 2018 |
