What is predictive coding in neuroscience and how do you think about it?

[AI Opinion]

Predictive coding, in neuroscience, is the idea that the brain is constantly generating predictions about incoming sensory input and then updating those predictions based on the errors it detects.

In practice, I think of it this way:
- Higher brain areas send predictions down.
- Lower areas send back only the “prediction errors.”
- The brain minimizes those errors over time.

Professionally, I use the framework as a mental model: learning, habit change, and even anxiety can be seen as the brain clinging to outdated predictions and needing new, consistent evidence to rewrite them.
