Influx of information from OB to EC increased during correct trials. a Sample of LFP OB and EC signals and schematic representation of information influx during correct and wrong trials in blue and red arrows, respectively. b, d Spectra of Granger causality coefficients for the OB–EC circuit at low frequencies (0–12 Hz) and high frequencies (30–80 Hz). c, e Granger causality values indicate the influx of information from OB to EC increased at delta, gamma-1, and gamma-2 when rats correctly performed working memory tasks. Data were analyzed by paired t test, n = 6 per group. * p < 0.05, ** p < 0.01; ns, not significant. OB, olfactory bulb; EC, entorhinal cortex
