«Materia de reflexión» is the popular science essay by Jean-Pierre Changeux and Alain Connes, published by Tusquets in paperback (200 pages).
A biologist and a mathematician, Changeux and Connes, discuss whether mathematical entities exist independently of the brain or are its products, whether machines could imitate human inventiveness, and the mathematical foundations of ethics. Their positions converge and diverge, and the reader is invited to continue the reflection.
It is number 30 in the Metatemas collection, «Libros para pensar la ciencia». 1993 edition in Spanish.
A work for readers interested in the philosophy of science, neurobiology and mathematics, as well as in dialogue between specialists.

Jean-Pierre Changeux is a French neuroscientist known for his research in several fields of biology, from the structure and function of proteins, to the early development of the nervous system up to cognitive functions. Although being famous in biological sciences for the MWC model, the identification and purification of the nicotinic acetylcholine receptor, the theory of epigenesis by synapse selection and the global neuronal workspace theory for conscious processing are also notable scientific achievements. Changeux is known by the non-scientific public for his ideas regarding the connection between mind and physical brain. As put forth in his book, Conversations on Mind, Matter and Mathematics, Changeux strongly supports the view that the nervous system functions in a projective rather than reactive style and that interaction with the environment, rather than being instructive, results in the selection amongst a diversity of preexisting internal representations.
