Decoded working memory content shows drift over time, correlating with later memory errors noted in reports.
The highest predictive neural errors occurred in higher-order areas like V3AB and IPS0, consistent with attractor model predictions.
Time-resolved fMRI decoding revealed a structured flow of information predominantly from higher to lower visual areas during memory maintenance.
Findings highlight the relationship between drift dynamics and memory errors, emphasizing the role of cortical hierarchy in working memory.
