Brain's Predictive Processing: How We Experience the World #shorts

Añadido: 2026-05-17

[00:00:00]Your brain is constantly running forecasts about what you see, about what you hear, about what a person is about to say, what the floor is going to feel like when your foot lands on it, forecasts based on every similar situation it's ever logged. Higher brain regions send those predictions down.

[00:00:17]Then your senses send fresh data up and your brain compares the two. This is a framework called Friston laid out in a 2010 paper in Nature Reviews Neuroscience. Karl Friston is a theoretical neuroscientist at the University College of London and his paper is one of the most cited theoretical papers in modern neuroscience. It hasn't been refuted in 15 years since. It's been extended, debated on, built on, and as of 2024, the framework is still actively shaping how computational neuroscience works.

[00:00:47]So, if the prediction your brain made matches the data your senses inputted, you don't experience anything special.

[00:00:55]The room looks like the room, the voice sounds like the voice, there's no moment of perception. You just experience the world. But if the prediction is wrong, that's when your brain pays attention.

[00:01:07]That mismatch gets flagged and that mismatch is what gets remembered. That claim has two anchors in literature. The clearest synthesis is a 2012 review in Frontiers in Psychology at a university in the Netherlands, which is one of the major European centers for predictive processing research. And the most striking direct demonstration of this is a 2021 paper in Neuron by James Anthony and colleagues. They had people watch basketball games while they recorded their brain activity. And the moments that violated viewers' predictions about what was about to happen were the moments that got encoded most strongly into memory. Now, I want to mention that Neuron is one of the top neuroscience journals in the world. And the same author published a follow-up in Nature Human Behavior in 2023 that built on that finding.
