Nasion Polarity Phenotypes in BIMOD: A Primary Classification Framework

This paper proposes a constitutional classification system basedon magnetic polarity expression at the Nasion acupoint, using theBIMOD (Bodily Interferometric Magneto-Optical Discrimination)protocol. Four bilateral loci at the Nasion exhibit mutuallyexclusive polarity states, yielding eight discrete and reproduciblephenotypes. Each locus maintains a single fixed polarity — thepresence of opposing polarity states at symmetric positions issufficient to define the phenotype. BIMOD responses are preserved consistently across both directobservation and photographic (optical) representation, enablingfuture development of automated optical or magneto-optical sensors.This property supports large-scale population measurement, big-datapattern discovery, and potential anthropological stratification. The framework connects anatomical landmarks, biophysical measurement,and scalable human phenotype classification into a unified platformfor constitutional medicine and population-level research.
