NettetBook excerpt: The nervous system is particularly fascinating for many biologists because it controls animal characteristics such as movement, behavior, and coordinated thinking. Invertebrate neurobiology has traditionally been studied in specific model organisms, whilst knowledge of the broad diversity of nervous system architecture and its evolution …
This New Gene Map Could Force a Rethink of How Vertebrate Brains Evolved
NettetAs in all vertebrates, the nervous system of reptiles consists of a brain, a spinal nerve cord, nerves running from the brain or spinal cord, and sense organs.When compared with mammals, reptiles have proportionately smaller brains. The most important difference between the brains of these two vertebrate groups lies in the size of the cerebral … Nettet19. des. 2015 · How did the vertebrate brain evolve from that of an invertebrate chordate ancestor?
