The the brain is the most complex object we know of. Therefore, throughout history, it’s always been compared to the most complex technology of each historical era. “ Descartes thought that the brain was a kind of hydraulic pump, propelling the spirits of the nervous system through the body. Freud compared the brain to a steam engine.” And today we have computational neuroscience. That doesn’t mean that these models aren’t useful. Many discoveries came about from thinking about the brain as an engine, and now as a computer. But these models are just models. They are refined and become closer to the reality that we observe in the brain, but we still have massive gaps in our understanding of the brain. Like the misconception with amyloid plaques in Alzheimer’s that was only realized in the past few years. And now with glial cells, which likely make up 80% of the brain (but we’re not even sure). https://blogs.scientificamerican.com/brainwaves/know-your-neurons-what-is-the-ratio-of-glia-to-neurons-in-the-brain/ https://blogs.scientificamerican.com/brainwaves/know-your-ne... Glial cells were largely ignored, and thought to only protect neurons with myelin, but we’re now realizing how important they actually are for cognition and memory. And computational models and neural networks don’t even take glial cells into account when forming models.
