What you’ll learn

  1. A Body ModelExplain interoception as the sensing and interpretation of internal body states.The brain maintains a revisable model from many internal signals.
  2. Predictions and ErrorsDescribe how predictions, attention, and mismatches shape body perception.Incoming signals update models according to context, uncertainty, and relevance.
  3. Regulation in ActionTrace reciprocal brain-body pathways through autonomic, emotional, and gut communication.Brain and body change one another through overlapping feedback routes.
  4. Limits and EvidenceUse a context-sensitive model without treating one sensation as a diagnosis.The best explanation compares causes, timing, evidence, and uncertainty.

Questions this course answers

What is interoception?

Interoception includes processing internal signals, whether or not they become conscious sensations.

What does a prediction error represent?

Prediction error is a comparison that can help update a model when incoming signals differ from expectations.

Why can the same bodily sensation have different meanings?

The brain estimates causes using current signals together with context and prior learning.

Which statement best describes autonomic regulation?

Autonomic pathways change organ activity and receive ongoing sensory information from those organs.

What is the safest conclusion from one body signal?

Signals matter, but careful interpretation compares explanations and keeps uncertainty visible.
