Meanings of non-rapid eye movement sleep in English

The first one is called non-rapid eye movement sleep, or non-REM, okay?

Our understanding of the neural mechanisms of non-rapid eye movement sleep (NREM) is steadily increasing.

In mice, deletion of the dopamine transporter (DAT) gene reduced non-rapid eye movement sleep time and increased wakefulness consolidation independently from locomotor effects.

Electroencephalogram and electromyogram were recorded for 8 h on each day, and the recording was scored for non-rapid eye movement sleep, REM sleep, and wakefulness.

Sleep is regulated by homeostatic mechanisms, and the low-frequency power in the electroencephalogram (delta power) during non-rapid eye movement sleep reflects homeostatic sleep need.
