AngII infusion increases ROS in the somatosensory cortex, an effect blocked by neocortical application of MnTBAP (100 μm). Losartan and BQ123 attenuate the increase only partially, but they coapplication completely blocks the increase (*p < 0.05 from control; ^#p < 0.05 from control and AngII alone; n = 5 per group).
