The relationship between the brain and the mind was extraordinarily complicated, and largely not understood. Back on Earth, it was clear the mind was housed within the brain, and to some degree, the structure of the mind could be mapped over the structure of the brain. However, it was much more difficult to make more progress than that. Centuries of research in the fields of neurology, psychology and philosophy of mind had yet to uncover the depths of the human mind.
Furthermore, Rui possessed only a shallow understanding of neurology. He was not equipped to fully understand the phenomena associated with the discovery of the Martial Path.
However, even the shallow knowledge he came to possess allowed him to make some conjectures.
The brain could be divided into three sections; The cerebrum, the cerebellum and the medulla oblongata. The cerebrum could further be divided into the Frontal Lobe, Temporal Lobe, Occipital Lobe and Parietal Lobe.
