However, such rapid word learning has not been systematically found invisual domain, with diferent confounding factors obscuring the orthographic learning of novel words. This studyexplored the changes in human brain activity occurring online, during a brief training with novel written word-formsusing a silent reading taskResults: Single-trial, cluster-based random permutation analysis revealed that training caused an extremely fast (afterjust one repetition) and stable facilitation in novel word processing, refected in the modulation of P200 and N400components, possibly indicating rapid dynamics at early and late stages of the lexical processing. Furthermore, neuralsource estimation of these efects revealed the recruitment of brain areas involved in orthographic and lexico-seman‑tic processing, respectively.Conclusions: These results suggest the formation of neural memory traces for novel written word-forms after a mini‑mal exposure to them even in the absence of a semantic reference, resembling the rapid learning processes known tooccur in spoken language.
