title: Simultaneous use of rheoencephalography and electroencephalography for the monitoring of cerebral function.
abstract: Many of the changes in human performance under stress or in hazardous environments may be attributed, in part, to altered cerebral functions. These changes may take place in either the cerebral neurologic or cerebral circulatory systems. Investigation of the interaction between intracranial blood flow and neural activity during these exposures would provide a better understanding of the human response to these conditions. Experimental and analytical procedures are described whereby the combination of rheoencephalography (REG) and electroencephalography (EEG) may provide additional information during the study of cerebral function. Examples are given to demonstrate the simultaneous use of these techniques during mental arithmetic and antiorthostatic bed rest. Results of these tests in both the time and frequency domains show that REG and EEG can be used to provide graded quantitative measures of cerebral responses to externally applied stressors.
