Table 1.

Loadings of the first three principal components for a typical subject.

Variable	PC1	PC2	PC3
F^t_th	0.00	0.00	−0.71
F^t_VF	−0.06	−0.58	0.03
Fⁿ_th	0.70	0.01	−0.01
Fⁿ_VF	−0.69	0.00	−0.01
M^t_th	0.00	0.00	0.71
M^t_VF	−0.06	−0.58	0.03
Mⁿ	0.13	−0.57	−0.06

The covariance of the detrended variables was calculated at 100 time samples. The variables with large loadings are shown in bold.
