Comparison of template-matching correlation between whole-trace and partial-trace calculation. A, Top, From left to right, the whole trace of the LW correlation of the 50 h recording with a single exposure, the 50 h recording with dual exposures (repeated twice for different Ribeiro-type decomposition later), the 25 h recording from prefrontal cortex, and the 25 h recording from hippocampus are shown, respectively. The parameter combinations, bin width of 250 ms and template length of 9 s, are used, and no significant long-lasting reverberation was observed. Bottom, The parts of the correlation curves that were not calculated by Ribeiro et al. (2004) are colored in blue. B, Deleting the blue curves and superimposing the red and black curves produces artificial long-lasting reverberation or anti-reverberation in four of five cases. Significance was assessed by Bonferroni test, and significant reverberation was depicted by a color scale ranges (0, 0.05) (yellow–red) and significant anti-reverberation by (−0.05, 0) (dark blue–light blue).
