Cortical Structures: the Cerebral Cortex
The cerebral cortex is the outer layer of neural tissue of the cerebrum in humans and other mammals. The longitudinal fissure that divides the cerebrum into the left and right cerebral hemispheres separates the two cortices. The ridges in the cerebral cortex form over time, from thinking habits.
The nature of energy healing is to dissolve old habits of thinking which do not suit life or the purpose of evolution and results in a restructuring of the brain physically.
