The brain’s code seems to be in constant flux. Neuroscientists are baffled Neurons fire much more erratically than researchers thought. What does that mean for how the brain works? By Diana Kwon

https://www.nature.com/articles/d41586-026-01554-0 It is a dogma in neuroscience that certain brain cells respond in the same way to the same thing. Specific neurons always fire, for example, when we see particular shapes and colours; other neurons activate to swing an arm or wiggle a nose. The brain needs this stability, the theory goes, to respond to the outside world in a consistent way.
