<div style="margin: 0px;"><font face="Cambria">500 ms of post-stimulus interval is contrasted to 500 ms of pre-stimulus interval. The problem is I see strong activity in the middle of the head for couple of my subjects. It is very strong for one subject as
shown ( link to figure 1: <a href="https://chalmersuniversity.box.com/s/jxmq5zp8k9m9tdfpogem7ee3r4z9q3ac" target="_blank" id="LPlnk958833" previewremoved="true"><span id="LPlnk958833">https://chalmersuniversity.box.com/s/jxmq5zp8k9m9tdfpogem7ee3r4z9q3ac</span></a> )and
week for other subjects ( link for figure 2: <a href="https://chalmersuniversity.box.com/s/o3yl57s6phr96f9rxh4wuthjcgllr2vv" target="_blank" id="LPlnk690402" previewremoved="true"><span id="LPlnk690402">https://chalmersuniversity.box.com/s/o3yl57s6phr96f9rxh4wuthjcgllr2vv</span></a> )
. I thought that noise bias towards the center of the head is usually taken care of when comparing conditions. Could somebody guide me how to solve this problem. Specially figure 1 where the noise bias is so strong that I don’t see any activity in somatosensory
cortex.</font></div>
