One of the extant artifacts of ancient Egypt, the most commonly used image of the "Eye of Ra", is a good example (Fig.6). The priestly messages do not cease to amaze by their descriptiveness in part of the transfer of knowledge of the human being. Thus the image of "Eye of Ra" coincides with the location of the main centers in the human brain, presenting graphic illustration of the hypothalamic-pituitary system (Fig.7).
The "Eye of Ra" consists of six components, which corresponds to the six sense organs of human, the signals from which are decrypted by the thalamus (from Greek «thalamos» - «bedchamber», «room») - the apple of the Eye.
