“Partner” describes one of the two fundamental relationship categories that you use to “map” individuals (people, animals, sometimes even plants, if you see them as having feelings and awareness) that you know within your psyche.

Your nervous system organizes all others into two fundamental categories based on how you perceive their evolutionary biological roles in relation to yourself.

The mother-child category of individuals you know encompasses all the individuals in which you experience a relationship of unequal dependance.

Your partner category encompasses all other relationships, which is those that are peer-based, competitive, territorial, or sexual. Your father is typically your first partner, followed by siblings, extended family, and school peers.

In a right-handed person, the partner side is the right side of the body; in a left-handed person, the left side.

Whether you “map” someone as a partner is purely subjective; it does not depend on whether the individual (person or animal) involved is your biological father/sibling.

Nor does your perception of that individual depend on whether that individual sees you as a partner. For example, a woman might see a man as a partner, but he sees her as a dependant child, or as his substitute mother.

You map relationships of “equal peers” on the dominant side of your body, if the conflict is relayed through

• your cerebellum (old mesoderm germ layer). Conflicts of worry or argument about or with someone you perceive as a “partner” will relay to the breast glands on your dominant side.
• your cerebral medulla (new mesoderm germ layer). Conflicts of devaluation and inability in relation to someone you perceive as a “partner” will relay to musculoskeletal tissue on your dominant side.
• your cerebral cortex (ectoderm germ layer). Conflicts of separation from (or desired separation from) “partner” (including auditory, smell, visual, touch, and taste separation) will produce tissue and functional changes on your dominant side. Motor conflicts (the”play-dead” reflex or the “freeze” aspect of fight-flight-freeze) having to do with someone you see as “partner” will cause paralysis and low muscle tone on your dominant side.

However, if your conflict is relayed through the pons of your brainstem, your laterality does not matter. Neurological dominance does not affect special biological programs involving the pons of the brainstem.
