Pyramidal cells activity is more correlated under prey-like stimulation than conspecific-like stimulation. A: population-averaged absolute cross-correlation coefficient |R| for prey-like and conspecific-like stimulation. B: population-averaged absolute cross-correlation coefficient |R|noise for prey-like and conspecific-like stimulation. C: R vs. Rnoise from all pairs under prey and conspecific-like stimulation. The strong and significant linear relationship between both quantities (r = 0.9, P ≪ 10−3, n = 114) indicates that changes in correlated activity are at least in part due to changes in noise correlations. **, statistical significance using a pairwise t-test at the P = 0.01 level and with n = 38.
