Overview: Effect sizes (Cohen d) for 18 electrophysiology variables

Mutant slices showed little overall electrophysiological difference from wildtype slices, with no electrophysiological variables significantly affected by this mutation. Note that in the theta burst analysis, the tenth burst is analysed as representative of individual burst amplitude.
