When both Input 1 and Input 2 are +100uV, what state does the waveform achieve?

• A. It will deflect downward
• B. It will exhibit a phase shift
• C. It will remain flat and neutral
• D. It will oscillate rapidly

Answer: (C)

When both Input 1 and Input 2 are at +100µV, the resulting waveform will remain flat and neutral. This is because the electroencephalogram (EEG) measures the difference in electrical potential between two inputs. When both inputs are equal, their difference is zero, leading to a flat line on the EEG display. This neutral state indicates that there is no net electrical activity detected between the two inputs. Therefore, in this situation, the waveform does not exhibit any deflection upwards or downwards, nor does it demonstrate any oscillation or phase shift, which are typically associated with differences in voltage or changes in brain activity. The consistent +100µV levels in both inputs cancel each other out, resulting in no observed change in the waveform's position.
