  • Thalamocortical and cortico-cortical loops in the brain compute formal grammars.

  • Quantitative increase of cortico-hippocampal stacks within grammars causes qualitatively increased computational power.

  • Human brain computation is equivalent to indexed grammars (HOPDAs).

  • Unaided human brain capacity is far short of full Turing-complete grammars.

  • Formal grammars provide explanatory accounts of a range of human and animal data.
