What is the relevance of the "Montage" in EEG interpretation?

The relevance of the "Montage" in EEG interpretation is that it determines how electrode signals are compared. In EEG, a montage refers to the arrangement of electrodes and the way their recordings are displayed and analyzed. Different montages can emphasize different aspects of the brain's electrical activity, allowing clinicians to observe and interpret patterns of brain waves more effectively. By selecting a specific montage, the clinician can decide which electrode pairs to analyze together, which is crucial for detecting abnormalities and understanding functional relationships between different brain regions.

While the other options may mention aspects related to EEG, they do not accurately capture the primary role of the montage. For instance, increasing the number of sensors or electrodes is not the function of the montage; rather, it is about how data is organized and interpreted. A visual representation of brain structures is more associated with imaging techniques than EEG montages. Minimizing artifacts is essential in EEG recordings, but the montage itself does not inherently address artifact reduction; rather, it focuses on how the data is interpreted.
