Continuous theta burst stimulation over right pars triangularis facilitates naming abilities in chronic post-stroke aphasia by enhancing phonological access.

•rTMS has been shown to improve naming in chronic aphasia, but outcomes vary.•We explored if severity and/or type of naming impairment predicts rTMS outcomes.•Error type profiles localized impairment type to semantic or phonological access.•Phonological access deficits responded best to inhibiting right Broca’s area.•These data are pertinent for identifying who is a good candidate for rTMS therapy.
