Table contains the results of all one sample t-tests of the Fisher’s z-transformed Spearman correlation coefficients from the correlation between the individual fMRI PEAK grand average time series data with the grand average time series data of all other data types. (mean±SEM) represents the averaged z-transformed Spearman correlation coefficients and its standard error of the mean. P-values are corrected for multiple comparisons.
