Correlations (and statistical significance 𝑃) between primary sensorimotor cortex excitability and metals or metal-related proteins in serum. Note that correlation values are equal for ceruloplasmin-bound copper and ceruloplasmin (see Section 2). In bold correlation values with 𝑃<.005 (Bonferroni correction for multiple comparisons).
