Evolution of Myelinated Nervous Systems
2007It is probably not surprising that the myelinated nervous system and jaws are two characters that originated in the common gnathostome ancestors. For myelination would both allow rapid wielding of powerful jaws and rapid swimming responses as a means to escape.

This chapter starts by discussing the question of what type of organisms can be happy, concluding that it rests with the capacity to experience feelings, which also implies a capacity for consciousness. Within vertebrates, this feature is presumably limited to amniotes (i.e. reptiles, birds and mammals).

Evolution of the Nervous System in Fishes
2007The notion of a linear Scala naturae in vertebrate brain evolution meanwhile has been replaced by the phyletic (cladistic) method of establishing ancestral and derived brain characters. From this analysis, a Bauplan or morphotype of the vertebrate brain emerges which exhibits many common ancestral neural traits (e.g., cranial nerves, brain subdivisions)

[Evolution of the nervous system].
Anasthesiologie, Intensivmedizin, Notfallmedizin, Schmerztherapie : AINS, 2002This review tries to establish a synthesis between the comparative/morphological approach and the molecular analysis of ontogenetic processes in development and evolution. We use the formation of the nervous system in metazoans as a paradigm to point out that highly conserved molecular mechanisms may be responsible to generate tissues and organ systems

Evolution of the Amphibian Nervous System
2007This article gives an overview of the central nervous system, i.e., spinal cord and brain, of amphibians (predominantly frogs and salamanders) in a comparative, functional, and evolutionary perspective. Emphasis is laid on the description of the visual system including retina, optic tectum, pretectum, and thalamus, on the thalamotelencephalic pathways,

Evolution of Nervous Systems and Brains
2013The evolution of nervous systems and brains reveals two major evolutionary trends, one leading to ring-shaped nerve systems in cnidarians and ctenophorans, the other as the main track leading to a bilaterally organized nervous system with a circumesophageal ganglion and ventral cords.

The Evolution of Nervous Systems
2016The process of evolution offers the principles required to make sense of life on Earth. The development of nerve cells, some 600 million years ago, was one of the biggest breakthroughs in the history of life. In combination with muscles, it was an obvious success by allowing animals to behave; that is, to move in a desired direction.

Typed expressions evolution of artificial nervous systems
Proceedings of the First IEEE Conference on Evolutionary Computation. IEEE World Congress on Computational Intelligence, 2002We introduce an evolutionary algorithm paradigm for hierarchical, typed expressions. Some common genetic operators on the generated expressions are demonstrated. The evolved structures serve as genotypical codings for artificial organisms. A few examples are given showing how the expression evolution has been used for evolving artificial nervous ...

Origin and Evolution of Nervous Systems
2019Nervous systems integrate environmental and internal inputs to coordinate appropriate sometimes systems-level responses. Complex central nervous systems containing a brain and nerve cord(s) gained cognition, effectively forever changing the way in which organisms interact and adapt to their environment.
