Abstract

Activity of behaviorally identified neurons in the hypoglossal nuclei supplying the genioglossal muscles was assessed in intact, unanesthetized cats across sleep-wake states. Nineteen of 37 recorded cells discharged on a breath-by-breath or tonic basis with the respiratory cycle in at least one state. Most respiratory-related cells discharged more slowly during quiet sleep, whereas rates during rapid eye movement sleep were similar to those of waking.

    A suppression of the tonic and inspiratory-modulated GG activity can be observed provided that such an activity has not already reached its nadir during the preceding state of NREM sleep (Rowley et al., 1998; Katz and White, 2004; Eckert et al., 2009). While the tonic and inspiratory modulated components of GG activity are suppressed, asynchronous twitches of variable magnitude often occur scattered throughout REM sleep episodes (T in bottom trace of Fig. 7.1) (Megirian et al., 1978; Chokroverty, 1980; Richard and Harper, 1991). This twitching is analogous to that occurring during REM sleep in distal limb muscles but its intensity, pattern and timing is likely governed by distinct central sources specific for orofacial muscles.

  • Catecholaminergic A1/C1 neurons contribute to the maintenance of upper airway muscle tone but may not participate in NREM sleep-related depression of these muscles

    Among upper airway muscles that are innervated by hypoglossal motoneurons (XIImns) (Dobbins and Feldman, 1995; Altshuler et al., 1994; Saboisky et al., 2007; Fregosi and Ludlow, 2014), the genioglossus (GG) muscle is the most important dilator because its activation increases airway caliber (Remmers et al., 1978; Brennick et al., 2009). The activity of both XIImns and GG muscle is reduced during non-rapid eye movement (NREM) sleep and it is further suppressed during rapid eye movement (REM) sleep (Sauerland and Harper, 1976; Suratt et al., 1988; Horner et al., 1989; Richard and Harper, 1991; Mezzanotte et al., 1992; Katz and White, 2004; Saboisky et al., 2007; Eckert et al., 2009). Neural mechanisms of depression of XIImns and GG muscle activity during NREM and REM sleep have been extensively studied in different animal models, with the majority of these studies focused on mechanisms of XIImns depression during REM sleep.
