Final answer:
A bipolar derivation montage, such as the O1-O2 montage, would be best to localize occipital spikes by phase reversal.
Step-by-step explanation:
Montage for Localizing Occipital Spikes by Phase Reversal
In order to localize occipital spikes by phase reversal, a bipolar derivation montage would be the most suitable. This montage involves placing two electrodes over the occipital region of the scalp, with one electrode recording the activity and the other serving as a reference point. By comparing the voltage differences between the electrodes, phase reversal can be identified, indicating the source of the spikes.
For example, a commonly used bipolar montage for occipital spikes is the O1-O2 montage. Electrode O1 is placed over the left occipital region, while O2 is placed over the right occipital region. By comparing the voltage activity between these two electrodes, phase reversals can be detected and the localization of occipital spikes can be determined.
