Figure 7From: The relationship between ciliary neurotrophic factor (CNTF) genotype and motor unit physiology: preliminary studiesDensity distribution of motor unit size for CNTF GG and GA genotypes for force levels less than and greater than 200 N for SMUP and MUmV. The graphs show the frequency distribution of motor units based on either SMUP or MUmV levels for genotypes GG and GA. The graphs show the interaction between CNTF genotype and motor unit properties.Back to article page
