> A key principle of DHCA is total inactivation of the brain by cooling, as verified by "flatline" isoelectric EEG, also called electrocerebral silence (ECS). Instead of a continuous decrease in activity as the brain is cooled, electrical activity decreases in discontinuous steps. In the human brain, a type of reduced activity called burst suppression occurs at a mean temperature of 24 °C, and electrocerebral silence occurs at a mean temperature of 18 °C.[32] The achievement of measured electrocerebral silence has been called "a safe and reliable guide" for determining cooling required for individual patients,[33] and verification of electrocerebral silence is required prior to stopping blood circulation to begin a DHCA procedure.[34] Thank you for the link. Is "measured electrocerebral silence" a measure of zero electrical current in the brain? Or just close to it?
