They played with the trade: MEG investigation of the processing of past tense verbs and their phonological twins

► MEG-evoked mismatch negativity to inflected past-tense forms. ► Pronounced neuromagnetic responses to deviants elicited 130 ms after onset of affix. ► Maximal responses localised to left hemisphere temporal sensors. ► Voiceless 'affixes' (-t rather than -d) elicited stronger right hemisphere response.
