Low-dimensional population dynamics in the brainstem gate REM sleep
Franz Weber
Nature Neuroscience, Published online: 25 May 2026; doi:10.1038/s41593-026-02314-z Lozano et al. show that REM sleep is gated by low-dimensional brainstem network dynamics, in which opposing neuron populations across the midbrain and pons determine when transitions into REM sleep can occur.
