<p>Eye movement artifact are some of the easiest to spot with the naked eye. Eye blinks are commonly found at Fp1, Fp2, Fz, F7, and F8 locations, respectively. The reason we see artifacts with eye blinks is because eyeballs are dipoles, with a positive polarity up front and a negative polarity in the back.</p><p style="text-align: center; "><img src="@@PLUGINFILE@@/Eyes%20are%20dipoles.jpg" alt="Eyes as dipoles" width="700" height="423" class="img-responsive atto_image_button_middle"><br></p><p style="text-align: center; "><i>Image 1o: The eyes are dipoles, with a positive polarity at the cornea and a negative polarity at the retina.</i></p><p style="text-align: center; "><i><br></i></p><p>Here is a video of eye blinks, watch the channel locations that are affected so you can later

<p>Sometimes a client will blink quite a lot, so much that there isn’t a moment in the record where their data is not affected by eye movements. When recording the data from these types of clients, ask that they try to NOT blink for 5 seconds after each
    blink. When artifacting data that is contaminated by eye blinks, you want to make sure that you are not collecting data that has the delta-like swing that follows each blink. We call this the “whiplash.” The following video shows how to avoid the
    whiplash in your editing process.</p><p style="text-align: center;"><span style="font-size: 1rem;">&nbsp;</span><span style="font-size: 1rem;">&nbsp;&nbsp;&nbsp;<video controls="true"><source src="@@PLUGINFILE@@/whiplash%20%282%29.mp4">@@PLUGINFILE@@/whiplash%20%282%29.mp4</video>&nbsp;</span></p>
