What is a brain? This question is more complex than it seems. Neuroscience has advanced over the last century with new ways to study brain cells, networks, and even animal behaviour. However, understanding how the brain truly works remains difficult.
In The Brain, In Theory, neuroscientist Romain Brette criticises the common view of the brain as a computer. He accepts that engineering ideas can help, but he believes they often miss important aspects, like how animals think. Real brains are not machines built to follow strict rules. Brette wants to refresh brain science by returning focus to biology, even though it is a challenging task.
Brette argues against the idea that brains work like machines. Neurons, the brain’s cells, do not simply follow commands or operate like computers handling data. He also rejects the idea of the brain processing information as it does not truly explain how the brain understands signals.
Instead, Brette suggests that the brain is linked to the body and its actions in the environment. He believes cognition, or thinking, is about doing things, not just calculating. This view sees the brain as a living system that adapts and interacts rather than as a static computer.
