摘要: Brain electricaI activity is related to cerebral perfusion. The nature of this relationship unclear, however, and surface-recorded has not been a reliable indicator brain We studied 27 subjects, all whom were examined with single photon emission tomography (SPECT) quantitative electroencephalography (QEEG), assess associations between QEEG cordance relative perfusion" Cordance two states: concordance, which may indicate high perfusion; discordance, low used multiple linear regression the association SPECT values, found that values strongly associ- ated tissue Concordance in band was associated both mean perfusion volume normally perfused tissue, it had stronger than any other variable. Discordance fi, perfusion, did but absolute power. These data suggest be useful for noninvasive assessment
