Decreased thalamic activity is a correlate for being asleep during general anesthesia – Except for ketamine
29.06.2023
In a study conducted at the University of Turku, Finland, the neural mechanisms of different anesthetics were investigated using functional brain imaging. Disconnection from external world and events ("being asleep") was specifically related to reduced activity in the central thalamic nuclei in subjects who received propofol, dexmedetomidine or sevoflurane, but not in subjects who received S-ketamine.
