hardcover. Zustand: Good. Wyatt, David; Pinfold, Levi (illustrator). Our good condition books are generally good for reading but not for gifting or collecting. They could have imperfections such as creasing, fanning, inscriptions, margin notes, yellowing, staining on edge or cover or pages, bumps, scuffs, etc etc (sometimes multiple of these). It's a wide category that encompasses anything that isn't almost-new down to anything that is slightly better than poor. We would NOT recommend gifting Good books - these should be considered reading copies. Our books are dispatched from a Yorkshire former cotton mill. We list via barcode/ISBN so please note that the images are stock images and may not be the exact copy you receive, furthermore the details about edition and year might not be accurate as many publishers reuse the same ISBN for multiple editions and as we simply scan a barcode or enter an ISBN we do not check the validity of the edition data when listing. If you're looking for an exact edition please don't order (at least not without checking with us first, although we don't always have time to check). We aim to dispatch prompty, the service used will depend on order value and book size. We can ship to most countries, see our shipping policies. Payment is via Abe only.

(London, Harrison and Sons, 1879). 4to. No wrappers as extracted from "Philosophical Transactions" 1878 - Vol. 169 - Part II. Pp. 563-575 a. 2 lithographed plates. Clean and fine. First printing of this pioneer paper introducing the concept of NEURAL NETWORKS and initiating the "NEURON DOCTRINE"."His early histological work on the nerves of the jellyfish Aurelia aurita led to his very early promotion of the idea that nerve cells are structurally and functionally independent units. This later became known as the ?neuron doctrine? Schäfer was led to study the structure of the subumbrellar nervous plexus in Aurelia aurita. He found that each nerve fiber was distinct from and nowhere structurally continuous with any other" he thought it reasonable to assume fiber-to-fiber transmission from "inductive action," possibly electric, the result being the same as if there were a real network."(DSB).
