…again, that’s probably something mechanical rather than organic. Sudden spikes, especially when they are repetitive, probably also indicate a problem. Artifact in Assessments Artifacting can make a big difference when…

…you look at the artifacting page, you see the selected threshold numbers for low frequency artifact (often related to eyeblinks, eye movement, cable movement, etc) and high frequency artifact (tension…

…It is called “artifact” because it is not really from the brain.  It is difficult to avoid this eye blink artifact when electrodes are placed near the front of the…
