Evidence for Molecular Coding of Neural Information

The essential significance of the chemical transfer of learning experiments is that they provide bioassay methods for the isolation of behavior-inducing substances. The results obtained by these methods have provided evidence for a molecular code of neural information. Once the specific behavior-inducing substances are chemically defined they can be further investigated by appropriate microanalytical techniques. It is hoped that this general approach will allow within the next few years the identification of several information-carrying molecules and thus open the way to a systematic study of the molecular code.
