Term devised by a Japanese experimenter Tomobichi
Fukurai for thought photography, the impressing of mental
images on photographic plates. His researches were embodied
in his book Clairvoyance and Thoughtography (1911, English
translation 1930). Modern Japanese experimenters now use
the term Nengraphy.
