I theorize that the brain's main systems of circuitry, along with the flow of 'chi', or 'funk' through the body occurs in a circular pattern, with an internal circuit from a loop with overlaps at the genitals and in the brain. [see visual]
The two peripheri of this internal loop likely cross again at each of the chakras. The top and bottom chakras are placed in relation to the crossings of the two peripheri, being the 0/1 male/female genitals, either internal or external to this loop, and the area above the cross inside the brain, perhaps indicating either being of the world above or below.
It is also noted that seams in this energy flow arise from the brain at what i would suspect to be the midpoint of each of the two hemispheres of the brain, pushing outwards. Their magnetic field force reaches a ceiling, and the forces push out in all lateral directions from that maxima, forming the complete semispherical chi zone of a human.
The extremeties are secondary to this primary loop, and may function energetically using field receivers in the bone structures of the metatarsals and metacarpals or through the metallic blood, and the skin and nerves. Forearms have circularly looping blood vessels. The iron in it and the cells thereof would accept signal at an appropriate wattage to the body. A similar statement probably is true of the legs, which have donatable non-circuit-breaking blood vessels often used in heart surgery. The second half of the appendages also both have two bones which could form AM-style loop receiver circuits. The skull itself could be one such 3D AM circuit.
