According to the 2016 ACNS Guidelines, what is the minimum horizontal resolution recommended?

The minimum horizontal resolution recommended by the 2016 American Clinical Neurophysiology Society (ACNS) Guidelines is 16 bits. This specification relates to the precision of the data collected during an electroencephalogram (EEG). A higher bit resolution allows for a greater dynamic range of values, enabling more nuanced detection and representation of the brain's electrical activity. This means that more subtle changes in the EEG signal can be captured and interpreted, which is crucial for accurate diagnosis and analysis of various neurological conditions.

In contrast, options such as 8 bits would not provide sufficient detail in the data, while frequency specifications like 16 Hz or 8 Hz pertain to the sampling rate, which is separate from the resolution of the data itself. The focus on bit resolution emphasizes the importance of quality in capturing EEG signals for reliable clinical interpretation.
