There's lots of opportunities in the brain for closures of these kinds, though I fear that this ultimately raises another set of even-more challenging questions: namely, how do our brains decipher between different circuit closures if they differ in their constraints? Fun to think about...

The short answer is yes, but we were quite limited in writing that paper to keep the text short and the references mostly to the last few years. I'm certainly not an expert on circular causality/constraint closure, but I do very much like the implications of the ideas

What changes and what stays the same as you scale from single neurons up to local populations of neurons up to whole brains?

Adaptive learning is coordinated across behaviour, time and neurobiology (from synapses and dendrites, to astrocytes and the systems level).

I need some help from the #neuroskyence Bluesky-verse. Anyone know the source of this ~quote from Walter J. Freeman Jr.: "the secrets of the brain are hidden by two of God’s own firewalls: neurobiology and non-linear dynamics". I read it yrs ago but can't seem to find my way back to the source.

Cooperative thalamocortical circuit mechanism for sensory prediction errors - Nature Experiments in mice show that a cortico-thalamic circuit generates prediction-error signals in primary visual cortex that amplify visual input that deviates from animals’ expectations.

Pairs well with www.nature.com/articles/s41...

β€œOur results indicate that individual V1 neurons do not signal how the actual visual input deviates from the animal’s predictions, as postulated within the predictive coding framework”

Thrilling to see a major theory get tested!
