ローマン・ブレット 脳型コンピュータモデル

Romain Brette's new book, The Brain, In Theory, systematically deconstructs the dominant brain-as-computer model, arguing that it is often vague, incoherent, and misleading. Brette contends that real brains are not engineered, and that the study of the nervous system should focus on biology, not engineering metaphors. He tackles the idea that brains can be explained using mechanistic concepts, arguing that neurons do not follow fixed rules or commands, and that neural activity is not a code. Brette also rebuts the doctrine of neuro-computationalism, which suggests that the mind is a kind of software running on neural hardware. Instead, he proposes an ecological perspective on cognition, where brains contemplate a world of possibilities for action. According to Brette, cognition is knowing by doing, and our brains don't compute, they contemplate. When a person sees a chair, they do not categorize it abstractly, but instead anticipate the movements that they would need to perform to sit in it. Brette's perspective on the mind is ecological, and he emphasizes that the principle that rules living brains is organization. He sees brain activity as the collective behaviour of a colony of living entities, rather than a distributed computer. The book is a plea for theory in a data-driven age, and it originated with a blog that Brette started writing to seek intellectual freedom from the paper mill. With this new perspective, Brette aims to breathe life back into brain science, and his work has the potential to change how we think about the brain and its functions.
