[Alpha activity and spindles in comatose patients after brain damage in reference to CT-results (author's transl)].

We observed seven comatose patients after various brain injuries who showed an alpha- or spindle-activity in the EEG. All patients were systematically examined by EEG and Computer-Tomography (CT). In all these cases a brain stem lesion was visible in CT. Three times the CT-findings could be verified by autopsy. The CT-findings agree with the well known localization of the lesion in the phono-mesencephalic region in these patients.
