               A Theory of the Cerebral Cortex

                          Abstract

This talk will describe a comprehensive new theory of the cerebral
cortex.  What do different types of cortical cells do?  How is sensory
data processed?  How are motor commands generated?  What does frontal
cortex do?  What is thinking?  In what representational system is
information stored?  How do learning and memory work?  What, exactly,
happens - step by step - during examination of visual scene?  What is
sleep?  In short, this theory explains - in specific clear detail,
the first-order picture of how the entire cerebral cortex works.
