1 Introduction Studies on the mechanisms of sleep-dependent memory consolidation have increasingly focused on the role of sleep spindles (Fernandez and Lüthi 2020; Peyrache and Seibt 2020). Sleep spindles are cortical oscillatory patterns, ranging from 9 to 16 Hz, occurring during non-rapid eye movement (NREM) sleep, and are generated by the thalamic reticular nucleus.

Abstract Background Difficulties in language development are related to social and emotional problems, lower academic outcomes, and lower quality of life from childhood to adolescence. These grave consequences might be significantly reduced by timely identification and professional support. The introduction of systematic screening for language delay (LD) in 3-year-old children in Hungary was based on the recent adaptation of the MacArthur–Bates CDI-III (HCDI-III).
