Identifiable Neurons in Invertebrates: From Invariant Cells to Dynamic Systems

Thirty years of investigation into identified neurons and small systems of identifiable neurons have made it clear that both are much more plastic and multifunctional than had been thought. The two main conclusions seem to be that a) both neurons and networks are intrinsically plastic and multifunctional, and b) the lines between identifiable and non-identifiable neurons and hence 'simple' vs. complex networks are becoming very blurry. In this volume, reviews provide distinctive overviews of the lessons learned from identifiable neurons and each makes diverse predictions as to the most exciting directions for the future. Theodore H. Bullock reviews identifiable neurons; James L. Larimer discusses the classical 'command neurons' of the crayfish abdominal positioning system; Janet L. Leonard looks at alternative models of the organization of motor behavior, and George J. Mpitsos examines the potential of dynamic systems theory and attractors for understanding neural behavior. All students of neuroscience and neurobiology interested in a summary of the state of the art in identifiable neurons will find the volume stimulating; particularly those individuals interested in a systems approach to understanding the function of nervous systems or the organization of behavior.
