Sleep bruxism (SB) is reported by 8% of the adult population and is mainly associated with rhythmic masticatory muscle activity (RMMA) characterized by repetitive jaw muscle contractions (3 bursts or more at a frequency of 1 Hz). The consequences of SB may include tooth destruction, jaw pain, headaches, or the limitation of mandibular movement, as well as tooth-grinding sounds that disrupt the sleep of bed partners. SB is probably an extreme manifestation of a masticatory muscle activity occurring during the sleep of most normal subjects, since RMMA is observed in 60% of normal sleepers in the absence of grinding sounds. The pathophysiology of SB is becoming clearer, and there is an abundance of evidence outlining the neurophysiology and neurochemistry of rhythmic jaw movements (RJM) in relation to chewing, swallowing, and breathing. The sleep literature provides much evidence describing the mechanisms involved in the reduction of muscle tone, from sleep onset to the atonia that characterizes rapid eye movement (REM) sleep. Several brainstem structures (e.g., reticular pontis oralis, pontis caudalis, parvocellularis) and neurochemicals (e.g., serotonin, dopamine, gamma aminobutyric acid [GABA], noradrenaline) are involved in both the genesis of RJM and the modulation of muscle tone during sleep. It remains unknown why a high percentage of normal subjects present RMMA during sleep and why this activity is three times more frequent and higher in amplitude in SB patients. It is also unclear why RMMA during sleep is characterized by co-activation of both jaw-opening and jawclosing muscles instead of the alternating jaw-opening and jaw-closing muscle activity pattern typical of chewing. The final section of this review proposes that RMMA during sleep has a role in lubricating the upper alimentary tract and increasing airway patency. The review concludes with an outline of questions for future research.

“…The ventral and dorsal striatal subregions exhibit functional differences in a variety of behavioral paradigms (De Beltran et al, 1992, 1993; Wadenberg et al, 1990). However, striatal studies pertaining to PPI have focused only on the VS.…”

“…Although the ventral striato-pallidal modulation of PPI has been an object of intense study, regulation of PPI by the remainder of the striatal complex has not yet been fully evaluated. Previous behavioral studies have established functional differences between the VS and dorsal striatum (DS) in a variety of other paradigms (De Beltran et al, 1992; De Beltran, Koshikawa, Miwa, Kobayashi, & Stephenson, 1993; Wadenberg, Ericson, Magnusson, & Ahlenius, 1990), so one might expect to find differential effects on PPI following dorsal and ventral striatal manipulations. However, anatomical studies have shown that medium spiny neurons in the caudal portion of the DS send GABAergic projections to the caudal dorsal pallidum (Moriizumi, Nakamura, Tokuno, Kitao, & Kudo, 1988).…”

It has been shown that the acoustic startle reflex is inhibited by weak auditory prepulses presented 30-500 ms prior to the startling stimulus and that this prepulse inhibition (PPI) is modulated by ventral striato-pallidal circuitry. However, dorsal striatal modulation of PPI has not been examined. Cell-specific lesions and intracerebral drug infusions were used to elucidate striatal modulation of PPI. Quinolinic acid lesions of the ventral and caudodorsal striatum significantly decreased PPI, whereas lesions of the rostrodorsal and middorsal striatum did not significantly alter PPI. Infusion of the GABA-A antagonist picrotoxin into the ventral and caudal dorsal pallidum also significantly reduced PPI, whereas rostral pallidal picrotoxin infusion had no significant effect. Thus, PPI in the rat seems to be modulated by both ventral and caudodorsal striato-pallidal circuitry, but not by rostrodorsal or middorsal striato-pallidal projections.

Birds have well-developed basal ganglia within the telencephalon, including a striatum consisting of the medially located lobus parolfactorius (LPO) and the laterally located paleostriatum augmentatum (PA). Relatively little is known, however, about the extent and organization of the telencephalic "cortical" input to the avian basal ganglia (i.e., the avian "corticostriatal" projection system). Using retrograde and anterograde neuroanatomical pathway tracers to address this issue, we found that a large continuous expanse of the outer pallium projects to the striatum of the basal ganglia in pigeons. This expanse includes the Wulst and archistriatum as well as the entire outer rind of the pallium intervening between Wulst and archistriatum, termed by us the pallium externum (PE). In addition, the caudolateral neostriatum (NCL), pyriform cortex, and hippocampal complex also give rise to striatal projections in pigeon. A restricted number of these pallial regions (such as the "limbic" NCL, pyriform cortex, and ventral/caudal parts of the archistriatum) project to such ventral striatal structures as the olfactory tubercle (TO), nucleus accumbens (Ac), and bed nucleus of the stria terminalis (BNST). Such "limbic" pallial areas also project to medialmost LPO and lateralmost PA, while the hyperstriatum accessorium portion of the Wulst, the PE, and the dorsal parts of the archistriatum were found to project primarily to the remainder of LPO (the lateral two-thirds) and PA (the medial four-fifths). The available evidence indicates that the diverse pallial regions projecting to the striatum in birds, as in mammals, are parts of higher order sensory or motor systems. The extensive corticostriatal system in both birds and mammals appears to include two types of pallial neurons: 1) those that project to both striatum and brainstem (i.e., those in the Wulst and the archistriatum) and 2) those that project to striatum but not to brainstem (i.e., those in the PE). The lack of extensive corticostriatal projections from either type of neuron in anamniotes suggests that the anamniote-amniote evolutionary transition was marked by the emergence of the corticostriatal projection system as a prominent source of sensory and motor information for the striatum, possibly facilitating the role of the basal ganglia in movement control.
