A new study from the Universite de Montreal found that parts of the brain may still be active after flat lining on an electroencephalogram (EEG), leading experts to debate the criteria for declaring a patient “brain dead.”

Researchers put 26 cats under deep anesthesia and monitored brain activity in the cortical region of the brain and the hippocampus. They found that every single cat had a “ripple event” of brain activity in their hippocampus after the EEG flat lined, the Los Angeles Times reported.

“Flat line was the deepest known form of coma,” said study researcher Florin Amzica, according to Discovery.
