The brain regulatory program predates central nervous system evolution [PDF]
Understanding how brains evolved is critical to determine the origin(s) of centralized nervous systems. Brains are patterned along their anteroposterior axis by stripes of gene expression that appear to be conserved, suggesting brains are homologous ...

Intron and gene size expansion during nervous system evolution [PDF]
Background The evolutionary radiation of animals was accompanied by extensive expansion of gene and genome sizes, increased isoform diversity, and complexity of regulation.

A developmental perspective on the evolution of the nervous system [PDF]
The evolution of nervous systems in animals has always fascinated biologists, and thus multiple evolutionary scenarios have been proposed to explain the appearance of neurons and complex neuronal centers. However, the absence of a robust phylogenetic framework for animal interrelationships, the lack of a mechanistic understanding of development, and a ...

Voltage-gated ion channel diversity underlies neuronal excitability and nervous system evolution [PDF]
Nervous systems function via electrical excitability mediated by ion channels, an ancient preneuronal feature that many cells use to rapidly adjust behavior.

Introduction to ‘Origin and evolution of the nervous system’ [PDF]
In 1665, Robert Hooke demonstrated in Micrographia the power of the microscope and comparative observations, one of which revealed similarities between the arthropod and vertebrate eyes.

The origin and evolution of chordate nervous systems [PDF]
In the past 40 years, comparisons of developmental gene expression and mechanisms of development (evodevo) joined comparative morphology as tools for reconstructing long-extinct ancestral forms. Unfortunately, both approaches typically give congruent answers only with closely related organisms. Chordate nervous systems are good examples.

The evolution of the serotonergic nervous system
The pattern of development of the serotonergic nervous system is described from the larvae of ctenophores, platyhelminths, nemerteans, entoprocts, ectoprocts (bryozoans), molluscs, polychaetes, brachiopods, phoronids, echinoderms, enteropneusts and lampreys.

Origin and Evolution of the Nervous System Considered from the Diffuse Nervous System of Cnidarians
Cnidarians have the most primitive nervous system in animal kingdom. Diffuse nerve net (called “diffuse nervous system”) covers the whole body. Cnidarians are considered the earliest metazoans to have evolved a nervous system and therefore offer possible insight into some of the fundamental properties of early nervous system.
