Development of the animal body plan is controlled by large gene regulatory networks
(GRNs), and hence evolution of body plans must depend upon change in the architecture of …

There is more than one way to develop neuronal complexity, and animals frequently use
different molecular toolkits to achieve similar functional outcomes. Genomics and …

Despite the importance of the insect nervous system for functional and developmental
neuroscience, descriptions of insect brains have suffered from a lack of uniform …

The origin of the pentaradial body plan of echinoderms from a bilateral ancestor is one of the
most enduring zoological puzzles,. Because echinoderms are defined by morphological …

The chordate central nervous system has been hypothesized to originate from either a
dorsal centralized, or a ventral centralized, or a noncentralized nervous system of a …

Nematostella vectensis, an anthozoan cnidarian, whose genome has been sequenced and
is suitable for developmental and ecological studies, has a complex neural morphology that …

Abstract Analysis of the origin and evolution of neurons is crucial for revealing principles of
organization of neural circuits with unexpected implications for genomic sciences …

The question of whether the ancestral bilaterian had a central nervous system (CNS) or a
diffuse ectodermal nervous system has been hotly debated. Considerable evidence …

An inroad into an understanding of the complex molecular interactions on which
development is based can be achieved by uncovering the minimum requirements that …

The central nervous system (CNS) in different animals develops under the control of genes
that are often conserved both structurally and functionally. The question of whether such …
