Motor cortex zone spreads over the top of brain:
which readily gives at least one treatment scheme in, for example, Insect System:
--- top of finger has the zone crossing the top
--- the zone can be mapped in 8Qi or "Triorigin" points:
--- the line for motor cortex, brown, crosses top of finger
--- there are 4 (Triorigin) points at equal distance along the
motor cortex path
--- energy circulation matches that of "Lateral Border meridian"
the very fundamental energy path passing over the region
--- also matches circulation in "Upper External chakra of Burn" which corresponds to brain
--- colour of points is colour of natural stones to tape on
--- actually one may use all methods described earlier for self-treatment,
moxibustion in harmonization mode - perpendicular to points.
The scheme is to prevent destruction of motor cortex; there can also be similar scheme to promote restoration and functional activity in there.
More advanced treatment is a field for professionals (though Triorigin schemes are known being generaly safe).
