Brain reactivity to emotion persists in NREM sleep and is associated with individual dream recall.
Cerebral cortex communications 2022 Maëva Moyne, Guillaume Legendre, Luc Arnal et al.
The waking brain efficiently detects emotional signals to promote survival. However, emotion detection during sleep is poorly understood and may be influenced by individual sleep characteristics or neural reactivity. Notably, dream recall frequency has been associated with stimulus reactivity during sleep, with enhanced stimulus-driven responses in high vs. low recallers. Using...
