title: Cerebral monitoring by compressed spectral array.
abstract: Application of a frequency analysis technique, the compressed spectral array (CSA), permits the display of cerebral activity recorded by the electroencephalogram (EEG) over long periods of time in a succinct, graphic manner. This report is a description of a system which is being developed to investigate long-term monitoring of the EEGs of critically ill patients. The computer-based methodology which has been used to implement this system is described, with illustrations of CSA-transformed EEGs.
