Causal evidence for subliminal percept-to-memory interference in early visual cortex

► We investigated visual short-term memory (VSTM) interference by irrelevant input. ► It is unclear whether this effect occurs at early stages of visual processing. ► Subliminal visual stimulus was presented during visual short-term maintenance. ► This affected the fidelity of VSTM when incongruent with the memory cue. ► A TMS study indicated that this interaction takes places in the early visual cortex.
