<p>When there is a lack of blood flow and oxygen to the area, there is often a consequential slowing of alpha at the area. As the area degrades, sometimes the alpha slows considerably below the band. But this depends on how severe the ischemia is (Classen and Foreman, 2012). If the slowing is in the theta range, if can be due to a trauma, a vascular anomaly, an aneurism or structural anomaly.<br></p><p style="text-align: center;"><img src="@@PLUGINFILE@@/slow-alpha.png" alt="Slow Alpha" width="1279" height="718" class="img-responsive atto_image_button_text-bottom"><br></p><p style="text-align: center;">Figure : Slow Alpha<br></p><p style="text-align: center;"><br></p><p style="text-align: center;"><img src="@@PLUGINFILE@@/anoxic-brain-damage.png" alt="Figure : Background Rhythm of 6 Hz in a 3 year old girl with anoxic brain damage" width="655" height="1105" class="img-responsive atto_image_button_text-bottom"><br></p><p style="text-align: center;">Figure : Background Rhythm of 6 Hz in a 3 year old girl with anoxic brain damage<br></p>
