This study aimed to investigate whether hub dysfunction of the salience network (SN) is associated with cognitive impairment in SeLECTS, using optically pumped magnetometer\u2010 magnetoencephalography (OPM\u2010MEG) within the framework of the triple network model (TNM), which encompasses the salience, default mode, and central executive networks (CENs).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>This cross\u2010sectional case\u2013control study enrolled 30 children with SeLECTS and 15 matched healthy controls (HC).

These children showed weaker network communication, especially in the beta frequency band, and a less central role of the salience network was linked to poorer cognitive performance.
