Figure 5. UEA recordings of MUA and LFP by TcES (10 Hz, 1.2 mA, 3 ms) in one cat.

Figure 5

(a) Left: optical imaging map (530 nm) and the schematic illustration of the UEA penetrated into the cortical surface; Right: P-value map (two-tailed t test, P < 0.05, n = 148 trials) of cortical activation. (be) 30–130 Hz (LFP) and 300–2500 Hz (MUA) power responses in 85-ms bins from electrodes in the NOR (18 electrodes) and POR (20 electrodes) regions (the stimuli lasted for 2 s). The first 15 ms of each 100-ms data containing the electrical artifact was removed. The data were averaged over 200 trials. (fg) Distributions of the MUA and LFP power changes (mean power within 2 s) in the NOR (119 electrodes) and POR (134 electrodes) regions from 6 cats.
