Table 3.
Correlation matrix for SN/VTA parameters. Age, R2*, and MT were correlated with each neuropsychological test (Pearson correlation). Benjamini-Hochberg (FDR) p-value adjustment was applied. Significant results are highlighted with an asterisk. Note that there was one missing value for VLMT recognition and that two participants had to be removed from the TMT-diff analysis (> 3 SD, see text).
