Today, anesthesia enables completely painless surgical procedures. It is already known from electroencephalography (EEG) studies on patients that during anesthesia the brain enters a deep sleep-like ...
Researchers have used functional magnetic resonance imaging (fMRI) to study the precise spatial distribution of synchronously working brain regions in anesthetized humans, long-tailed macaques, common ...
