In a recent study done by Dr. Feinstein a researcher with the prestigious Laureate Institute for Brain Research (LIBR) in Tulsa, OK. he gathered participants and divided them into two groups – those who would float for 90-minute sessions and those who would relax in a chair for the same period of time. He used MRI and water-proof EEG to study participants to evaluate them both pre and post-float.
The preliminary results were very promising. They found the highly connected areas of the brain had a huge drop in that connectivity post float. Ninety minutes in the tank affected the brain in the same way that pharmaceuticals do by turning down the hyped up salience network. The difference? Floating doesn’t have the side effects of the traditional medication.
