Recruitment of abdominal activity during REM sleep is influenced by the parafacial respiratory group


  • The results from this study suggest that abdominal muscle (ABD) recruitment during sleep is dependent on parafacial respiratory group (pFRG) activity and sleep state.

    • pFRG activity modulation does not impact on ABD recruitment during wakefulness or non-rapid-eye-movement sleep, but does during the rapid eye movement (REM) sleep state.

Why this matters

  • There has been little research examining the role of pFRG in ventilation and rhythm development across the various sleep states, and, as pFRG may play a vital role in these respiratory aspects, better understanding is greatly sought.

  • Enhanced understanding may give important insights that could lead to the development of alternative sleep apnea treatments.
