<p>Many will refer to the “active” electrode and the “reference“&nbsp; electrode. Commonly used “referential montages” include the ear references (linked ear, ipsilateral or contralateral ear), the Cz location or a “vertex” reference.&nbsp; Local function in the EEG does not shown well with linked ears (that is, if you had a focal slowing, Linked Ears would not be a good montage to view it). Linked ears montages show global firings well.</p><p>The linked ear montage can spread temporal lobe activity into reference electrodes. The activity seen at T5 and T6 are most likely to be seen in the electrodes on the ears but activity at T3 and T4 may influence the ear electrodes, as well as F7 and F8 in rarer cases.</p><p><br></p><p style="text-align: center;"><img src="@@PLUGINFILE@@/linked-ears-montage.png" alt="" width="519" height="512" role="presentation" class="img-responsive atto_image_button_text-bottom"><br></p><p style="text-align: center;">Linked Ears Montage<br></p><p style="text-align: center;"><br></p><p style="text-align: center;"><img src="@@PLUGINFILE@@/cz-reference-montage.png" alt="Cz Reference Montage" width="490" height="320" class="img-responsive atto_image_button_text-bottom"><br></p><p style="text-align: center;">Cz Reference Montage<br></p>
