Description
Book SynopsisIn science, sometimes it is best to keep things simple. Initially discrediting the discovery of neurons in jellyfish, mid-nineteenth-century scientists grouped jellyfish, comb-jellies, hydra, and sea anemones together under one term - coelenterates - and deemed these animals too similar to plants to warrant a nervous system. In Dawn of the Neuron, Michel Anctil shows how Darwin''s theory of evolution completely eradicated this idea and cleared the way for the modern study of the neuron. Once zoologists accepted the notion that varying levels of animal complexity could evolve, they began to use simple-structured creatures such as coelenterates and sponges to understand the building blocks of more complicated nervous systems. Dawn of the Neuron provides fascinating insights into the labours and lives of scientists who studied coelenterate nervous systems over several generations, and who approached the puzzling origin of the first nerve cells through the process outlined in evolutionary
Trade Review"Dawn of the Neuron shows how the evolution metaphor controversy played out in the emergence of the neuron doctrine and how inadequate research methods misled many authors on fundamental questions. The book is therefore a caution with regard to the overzealous speculation about universal principles of neural organization. Anctil has been active in research on coelenterates and therefore is an excellent guide in adjudicating these controversies." Gordon M. Shepherd, Yale University "In a series of impressively detailed episodes, Anctil carries readers from the seventeenth-century microscopists who first identified cells as the basic units of life, to the twenty-first century pioneers now applying molecular genetics to the still-unfinished task of accounting for the beginnings of neural cells. Exceptional scholarship illuminates the labors of intrepid minds pitted against one of biology's most inscrutable riddles." Booklist (starred review) "The study of coelenterates-a group that includes jellyfish, comb jellies, anemones, and hydra-doesn't typically make for riveting pop-sci reading. But in the hands of Michel Anctil, the unassuming creatures take center stage as the birthplace of modern science's appreciation of neurobiology. Anctil gives personality to animals once thought not that different from plants and brings back to life the labors of researchers who looked to those simple organisms to make groundbreaking discoveries, the reverberations of which are still felt today." - The Scientist
