Guest guest Posted May 1, 2007 Report Share Posted May 1, 2007 Pete and all,I did an assessment on an eleven year old today and noticed that he had a persistent and dominant spike of activity around 27 hz. That occurred at all electrode placements and under all conditions. It was a bit more variable (waxing and waning) at temporal sites and I noticed that it seemed to coincide with his 9 hz activity. His alpha activity is almost the same EO and EC. The general shape of his histogram is slow. His peak beta frequency at all sites came out between 25-27 hz after processing the report. He showed high, highbeta coherence frontal 60, central 59, parietal 58.So, my questions....Would the 27 hz activity be considered an harmonic of 9 hz, and, if so, does it affect protocol selection? ( ie.his high beta temporal % is 15, would I train that down as usual?)Thanks, Kittredge Quote Link to comment Share on other sites More sharing options...
Guest guest Posted May 1, 2007 Report Share Posted May 1, 2007 ,What hardware are you using. I have seen occasional 27-30 hz spikes like you describe with my Pendant.It happens only occasionally but is not eeg related at all.
