The accepted neurological dictum is that memory resides in the cortial neurons of the brain. Evidence from studies on genetics, epigenetics, organ transplants, immunology, unicellular organisms, planarian flat worms, nano computers and clinical psychology is cited here in support of the hypothesis that memory can also be stored in all the cells of the body, not just nerve cells. The relevance of this theory to pre- and perinatal psychology is explored. Key words: epigenetics, nanotechnology, immunology, unicellular organisms, cell memory
