Born 19 Feb 1910; died 6 May 1977 at age 67.

American-British #neurologist who linked learning with a particular #brain #wave as revealed by measurements by #electroencephalograph. He had special interests in the study of the #neurophysiological correlates of such #paranormal states as #hypnosis, #sleep, #trance, and #hallucination. He built the most advanced robot of his day. Called a testudo from Latin for "turtle", the automatic device mimicked reactions like a living creature. Using a #photoelectric eye, a touch-sensor, and motor-driven steerable wheels, it could negotiate around obstacles. It could approach a light bulb, but back away when it became too bright - unless it was "hungry" for a recharge of its batteries when it approached until it could make contact with a charger placed near the lamp.
