Results of 2-way mixed model statistical analyses of local field potential recordings within the dorsomedial PFC (dmPFC) and dorsomedial striatum (dmSTR) during the delay and reward intervals across the 4 analyzed frequency bands: theta, alpha, beta, and gamma. TRT, treatment (stress vs. no-stress control); SESS, session (baseline vs. second testing session).
