What color coding is typically used for EEG electrodes?

The International 10-20 System is the standardized method used for the placement of EEG electrodes on the scalp, where each electrode position corresponds to specific areas of the brain. This system employs a specific nomenclature and a designated color coding for ease of identification during both setup and interpretation of EEG recordings.

The reason the International 10-20 System is the correct choice lies in its relevance to EEG practices, ensuring consistent electrode placement for accurate readings and interpretations. This systematic approach allows for reproducibility in both clinical and research settings, facilitating communication among professionals.

In contrast, the RGB color model is primarily used in digital displays and lighting, the CMYK color scheme is related to color printing processes, and the Pantone Matching System is utilized mainly in graphic design and manufacturing for color consistency. None of these options are relevant to EEG electrode placement and coding, making the International 10-20 System the appropriate and correct answer in this context.
