Cocaine challenge produces selective alterations in induced oscillation power and coherence in COC and SAL animals A, Raw (top) and normalized (bottom) representative time-frequency spectrograms showing effects of cocaine challenge on BLA-induced oscillations in OFC in a COC (left) and SAL (right) animal. Arrowhead shows time of BLA stimulation. B, Effects of acute cocaine challenge on induced LFP power and coherence according to region and frequency band. Bold arrows indicate a significant COC/SAL difference; arrows indicate significant difference from prechallenge baseline. Horizontal line represents no change.
