In essence, the combination of these three principles forms the basis of what few of us would ever suspect: a reading circuit that incorporates input from two hemispheres, four lobes in each hemisphere (frontal, temporal, parietal, and occipital), and all five layers of the brain (from the uppermost telencephalon and adjacent diencephalon below it; to the middle layers of the mesencephalon; to the lower levels of the metencephalon and myelencephalon). Anyone who still believes the archaic canard that we use only a tiny portion of our brains hasn’t yet become aware of what we do when we read.
