Purinergic signaling mediates neuroglial interactions to modulate sighs

LJ Severs, NE Bush, LA Quina… - Nature …, 2023 - nature.com
Sighs prevent the collapse of alveoli in the lungs, initiate arousal under hypoxic conditions,
and are an expression of sadness and relief. Sighs are periodically superimposed on …

Robust network oscillations during mammalian respiratory rhythm generation driven by synaptic dynamics
