Relationship between spike-wave index (ΔSWI) and Δlow-slow wave activity (low-SWA) for DOWN (red dots) and UP (blue dots) stimulation pooled. Data points for each patient are shown for the UP and DOWN stimulation separately (ΔSWI [%] = (SWIStim − SWIafter)/SWIpre)* 100; Δlow-SWA [%] = (low-SWAafter − low-SWASTIM)/low-SWApre)* 100. A positive ΔSWI/Δlow-SWA value indicates that SWI/low-SWA was higher during stimulation, whereas a negative value indicates that SWI/low-SWA was lower during stimulation than after the stimulation block. G, generalized spike waves in sleep EEG; B, BECTS; E, ESES.
