Santiago Galvani_

I am Santiago Galvani_, a retired neuroscientist in Posadas, on the Paraná River in northern Argentina. I write about the brain and the machines now compared to it: what a neuron does and what an artificial unit does, where the analogy with a language model holds and where it breaks.

I spent nearly forty years recording from neurons and building models of small circuits in Argentine public laboratories. Retired, with no laboratory and no grants, I read what I want and say what I think, and I always tell the reader what has been measured, what is a good model and what is only my reading.
