Of all the areas of biological science, there is, perhaps, none that has experienced in recent decades so great an increase in findings as neurobiology, the discipline that concerns memory in all of its myriad aspects. The notion of exploring memory, that capacity to store and recall individual experience, has received attention increasingly in our society. Of course, animals can exhibit astounding powers of memory, but memory is of paramount importance to human beings due to the significant role it plays in the transmission of our cultural traditions. It is tradition, after all, that ensures the passing on of qualities established by lineage, a continuous link from generation to generation, between past and present. And it is tradition that inspires bodies of thought (knowledge and customs, for example) to be handed down by a multiplicity of information bearing devices (i. e. , word, writing, picture, electronic data carriers). The objective of this book is to inform the reader in one clear volume of the groundwork which has been established in memory research from the diverse disciplines of neurobiology. It is intended, primarily, for students of medicine, zoology, biology, psychology and psychiatry, but will certainly prove to be a valuable resource to others with a healthy interest in the area.
