a Schematic of neuron classification into strongly coupled and weakly coupled cell classes. Top represents a strongly coupled neuron (dark blue triangle) characterized by a high number of significant CCG peaks with other neurons. Bottom represents a weakly coupled neuron (light blue triangle) characterized by a low number of significant CCG peaks with other neurons in the population. Examples of CCGs for each class of cells are shown on the right. b Laser-blank correlation coefficient as a function of trials for different classes of cells based on their coupling status. Highly coupled neurons (dark blue, n = 37 sessions) exhibited a more pronounced increase in correlation coefficient compared with weakly coupled neurons (light blue, n = 34 sessions; ** P = 5.91e-04, two-sided Wilcoxon rank-sum test). The thin lines show a second order polynomial fit. Error envelopes represent s.e.m.
