Randomized trial reveals shifting neural activity patterns in hypothalamic neurons during sleep-wake states, indicating dynamic organization.

The aim is to explore the stability of activity patterns in hypothalamic neurons across different sleep-wake states.
Utilized longitudinal single cell calcium imaging in freely-moving, sleeping male mice to observe neuronal activity.
Investigated the effect of sleep deprivation and diazepam on hypothalamic neuron activity.
Examined the activity of genetically-defined populations of neurons including inhibitory and excitatory types.
Inhibitory and excitatory neurons did not maintain stable state-specific activities across sleep-wake states.
Sleep deprivation had minimal influence on the activity pattern selectivity of neurons.
Diazepam treatment activated previously non-active cells, enhancing NREM sleep activity.

Yan et al. (2026) studied this question.
