The Neocortex and Touching a Coffee Cup
34:02 - 39:45 (05:43)
The neocortex needs to have a model of a coffee cup and the location of the finger relative to that cup in a reference frame of the cup to predict when sensing or touching a coffee cup. By moving around the cup and touching it in different areas, the neocortex builds up a complete model of the cup in a three-dimensional map that registers the reference frame anchored to the cup.

The brain needs to have a model of an object in order to know how to move a certain body part to touch it, as well as predict how it will feel before making contact.

The neocortex predicts sensory inputs by establishing a reference frame, specifically when touching a cup, it needs to know the location of the finger relative to the cup to build a three-dimensional map of the object.

Summary
The neocortex predicts sensory inputs by establishing a reference frame, specifically when touching a cup, it needs to know the location of the finger relative to the cup to build a three-dimensional map of the object. This means that every part of the skin making contact with the cup has a reference frame used to make predictions.
