Abstract
A sender and a percipient were located separately in two sensory-shielded rooms, and extrasensory transfer of information was attempted while both were connected to electroencephalographs. The sender transmitted information without using the senses during a randomly selected half of a two-minute period. The percipient attempted tougess both the content and the time period. Over 20 trials, the percipient was not able to guess the correct sending time with any statistical significance. However, a statistically significant difference was observed in the α wave amplitde in her electroencephalogram between the sending and non-sending time ones. This suggests the existence of extrasensory information transfer in the subconscious. This extrasensory information transfer is not completed just after the reaction in the sender's brain, but is composed of two reactions. The first reaction occurs in the occipital to parietal region of the percipient and is followed by a reaction in the frontal region.
