Zusammenfassung:Highlights • Schizophrenia patients showed reduced recognition accuracy compared to controls. • Picture recognition accuracy was better after sleep than after wakefulness. • The memory-facilitating effect of sleep was lower in patients than in controls. • Sleep spindles were reduced in schizophrenia patients in comparison to controls. • Sleep spindle density predicted the memory enhancing effect of sleep.
