Weird movement noticed in the brains of dying patients

The study, published in Proceedings of the National Academy of Sciences, analyzed the electroencephalogram (EEG) and electrocardiogram (ECG) signals in four patients who were in a coma and died in the neuro-intensive care unit since 2014. The researchers found a surge of gamma waves in two of the patients as they transitioned into death, suggesting a resultant global hypoxia marked by stimulated gamma activities in those patients. According to the researchers, brain function around the time of cardiac arrest is poorly understood, and it is unclear whether patients can possess covert consciousness during the dying process. The surge of gamma waves observed in two of the patients established a long-range connection across both hemispheres of the brain, which may help in understanding the brain activity
