Montages are necessary to understand the many ways in which we can assess and view the EEG. There is no best montage for all purposes. While linked ears can provide a global view, it is prone to contamination and the creation of false positives Average and weighted average montages (such as the Laplacian and Hjorth montages), will highlight any local phenomena, and will uncover any significant temporal component, but will fail us to see global information and may also fall prey to the “tall man” outlier channel. Bi-polar montages are excellent for displaying phase reversals, which are indispensable in issues of head injury and seizure focus.
