Predictive Coding: Why Our Brain Is Constantly Predicting The Future

Predictive coding is an influential theory in psychology and neuroscience that explains how our brain learns from mistakes.
Our brain constantly makes predictions about the future. Then, incoming information (sensory or cognitive) is compared to this prediction. If there is a mismatch between actual information and the prediction, this leads to a prediction error.
Prediction errors tell our brain that our prediction was inaccurate and it will try to adjust the prediction for the next time. Such updating of prediction models is learning. One can learn from mistakes, or from feedback.
Brain signals such as the error-related negativity and feedback related negativity (ERN and FRN) reflect prediction error processing in the brain. Signals like the error positivity (Pe) reflect updating of prediction models.

USE OF STOCK IMAGES AND VIDEOS
Occasionally we make use of stock images and videos (pixabay.com or pexels.com). We use these to make our videos more lively (better than looking at a blank screen). These stock videos should not be taken as an exact scientific reflection of the discussed content. In some cases they are not fully accurate. We try to have a high viewing pleasure, while at the same time create as little confusion as possible. Thus we aim to only use them when it is clear that they are not directly related to the discussed content.
CHANNEL GOALS
The Psyched! channel focuses on providing education about psychology and neuroscience. Here you learn all about human behavior, the mind and the brain. It is our goal to reach everyone, from people who are casually interested to academic researchers. As such we provide simple explanation videos as well as profound lectures. If you like our content, consider to subscribe!

Thanks for your work,it helps with mine!❤

[@TeatimeMindfulness]

Fascinating. We are all Bayesian predicting machines.

[@MLDawn]

Would have been even cooler, had you also talked about the concept of the generative model, which is essential for making predictions under the scheme of predictive coding. Great video!

[@real.psyched]

Thanks for the tip!

[@maximilyen]

Very well

[@SA-Aries]

Is it possto alter body I mean big or sort or fat buy altering brain signals. If its all energy then it can be given from outside in the brain. I know it’s vague but just curious to know

[@Neuronalchannel]

Cool. How does that relate to the free-energy principle?

[@real.psyched]

Thanks! Well, that is an entire new video!
