I don't have any references to hand but I think this was at one point a
hugely exciting area of research that turned out to be utterly wrong,
like cold fusion and phrenology. Basically the experiments were not done
particularly well.
Try a history of science text book: there is a book called "The Drunken
Goldfish" which discusses it. Sorry I can't be much help.
