xon in vertebrates and causes saltatory conduction of the action potentials. Nerve fiber sheaths with certain features of myelin are found in other animals, notably in some arthropods. True myelin, however, seems to be confined to true vertebrates, from the elasmobranchs up, and is strongly conserve

The importance of genetic changes which alter the metrics of interactions between developing organ systems for evolutionary change has been stressed by Gould (1977). Yet

In order to identify the cell surface molecules mediating the adhesion that regulates many of these interactions, a variety of assays have been used and several molecules have been proposed to be involved in neural cell adhesion (Merrell et al., 1975; Hausman and Moscona,

Progress in this specialized area of developmental biology has occurred far more rapidly than in any o

It serves as a useful rubric to distinguish processes that are environmentally regulated from those that unfold from a rigidly programmed read-out of the genome. Thus, some connections might be termed “plastic” and others “hard-wired”. The experience that modifies connections is, of course, ulti

The competition depends in part upon the amount of neuronal activity or its patterning, and in part upon ill-defined components of the pre- and postsynapti
