Statistical properties of the empirical Bayesian testing. a The estimated distribution (blue) and surrogate null distribution (green) of the test statistic, Peak. The blue curve denotes the estimated total distribution, which is a normalized histogram of the estimated statistic of all possible pairs of observed neurons. The green curve denotes the estimated null distribution, which is a normalized histogram of the estimated statistics of the pairs of the observed and surrogate neurons. b The estimated local false discovery rate. Vertical and horizontal axes denote local false discovery rate and the test statistic (Peak). Each blue point corresponds to a pair of source and destination neurons. c A matrix of the estimated test statistic, Peak. Rows and columns denote destination and source neurons, where the source neurons include ten surrogate neurons. The color code denotes the value of the test statistic, Peak
