Abstract
RESULTS reported earlier1–5 have suggested that acquired information can be transmitted to naïve animals by giving them material extracted from the brain of trained subjects. In most of these experiments, as in others6–11, transfer of information was suggested by varying degrees of statistical probability and it was challenged by negative results obtained in other laboratories12.
