“…The mechanisms producing this fast activity are intriguing, as they appear to require fast firing of many action potentials, indicating a highly active local network (Bragin, et al 2011;Fink, et al 2015;Foffani, et al 2007;Ibarz, et al 2010;Shamas, et al 2018). However, it is not necessary for these phenomena to produce a true coherent oscillation, as the firing cells do not have to be synchronized (Fink, et al 2015;Gliske, et al 2017;Jiruska, et al 2010;Shamas, et al 2018). In terms of detection algorithms, this means that HFOs that are potentially epileptic may have broadband frequency content extending to at least 500 Hz (Blanco, et al 2011;Blanco, et al 2010).…”
