Potential bioactivated neurotoxicants, 2-N-methyl-beta-carbolinium and 2,9-N,N'-dimethyl-beta-carbolinium ions, as well as N-methylation activities which form these charged species, were analyzed for the first time in the parietal association cortex and the substantia nigra of human brain using GC/MS and HPLC. The brains were taken during forensic autopsies(More)
Scalp electroencephalograms (EEGs) of brain dead patients are macroscopically flat under 7 or 10 microV/mm electroencephalograph sensitivity, but significant noises are detected in EEGs under 2 microV/mm sensitivity, interfering with the analysis. EEGs of 20 brain dead patients (17-76 years old) were therefore analyzed quantitatively as equivalent electric(More)
Nasopharyngeally-derived electroencephalogram (EEG) was recorded and digitized in 12 "brain death" subjects with flat-line scalp EEG and loss of auditory brain stem response. The nasopharyngeal EEGs of these cases were classified into three types: Type Ia with complete flat-line, Type Ib with almost but incomplete flat-line EEG, and Type II with(More)
