What combination of settings enhances a low voltage slow wave that is masked by muscle activity?

The correct answer enhances a low voltage slow wave that might be obscured by muscle activity through optimal settings of sensitivity and frequency ranges.

A higher sensitivity setting, like 5 microvolts per millimeter, allows quieter or lower amplitude brain waves to be more easily detected and analyzed. This is critical when dealing with low-voltage slow waves because it increases their visibility against the background noise, such as muscle artifacts.

The low frequency setting of 0.3 Hz is particularly effective in capturing slow waves, as it allows for the adequate filtering of faster frequencies that may introduce noise from muscle activity. This is essential for isolating the desired EEG signal without interference.

On the other hand, the high-frequency setting of 35 Hz ensures that any muscle artifacts or high-frequency electrical noise can be effectively filtered out, focusing the analysis on the slower brain activity of interest.

Thus, the combination of sensitivity, low frequency, and high frequency in this answer maximizes the ability to visualize low voltage slow waves while minimizing the impact of muscle activity, making it the most suitable choice for the stated requirement.
