In their article "Accessibility of spoken, written and sign language in Landau-Kleffner syndrome: a linguistic and functional MRI study", Sieratzki et al.  claim that in LKS persistent aphasia is caused by a hyperexcitability of the speech cortices in response to phonological processing activity rather than by ablation or disconnection. This suggestion based on fMRI studies of language carried out on a patient with normal EEG for 12 years is questionable in certain respects.
