Sample recordings from 7-week-old hESC-derived Cerebral Organoids (COs). WWOX's coding sequence was re-introduced into week 6 WWOX-KO COs using lentiviral transduction (lenti-WWOX) (G) Normalized area under the curve of the mean spectral power of WT line, 2 KO lines and 2 KO lines infected with lenti-WWOX at week 7 in baseline condition, for the 0.25-1 Hz frequency range. Data represented by mean ± SEM. The numerals in all bars indicate the number of analyzed slices and organoids (i.e. slices (organoids)). Statistical significance was determined using one-way ANOVA with Tukey's multiple comparisons test. Data information: ***p ≤ 0.001, ****p ≤ 0.0001.
