Descriptive statistics for ERPs
| ERP measures | Placebo | Acetaminophen |
|---|---|---|
| ERN at FCz (μV) | −9.05 (3.34) | −10.80 (4.82) |
| Pe at Cpz/Pz (μV) | 10.94(5.05) | 7.5(5.81)* |
Note: Mean values are presented, standard deviations are in brackets. ERN and Pe mean amplitudes are constructed by first subtracting the average wave for a correct Go response from the wave for an incorrect NoGo response.
*P < 0.05
