- The document discusses using water as a potential sensor of brain activity, referred to as Antonov's method. It presents experimental designs where water was placed on the left and right hemispheres during tasks like reading or listening to music. - The mean energy values in the water samples placed on the left and right hemispheres were calculated and compared for the different tasks. Physiological parameters like skin conductivity, heart rate, and respiration rate were also measured. - The results showed differences in the water energy spectrum between the left and right hemisphere samples, indicating water may contain information about brain lateralization and could potentially be used to remotely sense brain activity.
