Page "Telepathy" Paragraph 16

Some parapsychologists still proposed that telepathy may have a physical explanation.

The Italian neurologist Ferdinando Cazzamali in the 1920s had claimed that telepathic communication occurred due to a type of electromagnetic radiation.

However the neurophysiologist William Grey Walter in his book The Living Brain ( 1953 ) wrote that electrical ' brain-waves ' are too weak to explain telepathy.

Hans Berger also held this view but extended the theory by proposing that telepathy occurs when " electrical energy in the agent's brain is transformed into ' psychic energy ' which can be diffused to any distance, passing through obstacles without attenuation ".
