E. Vrijdag Vol.:(011233456789) narcosis - I would like to congratulate Schneider et al. (2014) with their publication of the technological advance in recording EEG in the condition of full body water immersion. This will make it possible to record the EEG in various situations and help to understand the effects of diving on the brain and by that advance the field of neuroscience. The authors speculate that the modulating effect on the N200 latency and amplitude might possibly be due to an increase in intracranial pressure (ICP) caused by the increased environmental pressure experienced during water immersion. However, because there is a total submersion and there are no air cavities in the brain, there is no expectation of an increased ICP due to submersion. Our group did experiments on pigs where we measured the ICP during hyperbaric treatment to an equivalent of 18 m of seawater and we did not see a change in the ICP during this treatment (Weenink et al. 2013). I would like to postulate another option for the reduction of the N200 latency and EEG frequency spectrum amplitude.
