Diagnostic imaging and electroencephalography. (A) Magnetic Resonance Imaging of the Brain xx days after onset. T2- weighted axial views at three levels demonstrating normal gray/white matter differentiation, no focal lesions and preserved CSF spaces. (B) EEG with muscle relaxant; During the deepest period of paralysis runs of low amplitude spikes are seen at Cz with a fronto-central field in the absence of detectable proximal upper limb EMG or any clinical movements.
