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.

Innovation Cooperation in Brain Research is Intensifying in Southwest Finland

The University of Turku and the Turku University Central Hospital (TYKS) have signed a cooperation agreement on the establishment of the Turku Brain & Mind regional network. The network promotes brain health research and cooperation in Southwest Finland. The regional networks of the Neurocenter Finland have been in operation since late 2021.

Imaging the Twilight Zone − General anesthesia and normal sleep affect brain in an amazingly similar way as consciousness fades

28.12.2020

What happens in the brain when our conscious awareness of the surrounding world and of ourselves fades during general anesthesia and normal sleep? This fundamental question was studied with novel experimental designs and functional brain imaging by Finnish scientists. They succeeded in separating the specific changes related to consciousness from the more widespread overall effects, commonly misinterpreted as the neural correlates of consciousness. The effects of anesthesia and sleep on brain activity turned out to be surprisingly similar.
