Motor representation of rhythmic jaw movements in the amygdala of guinea pigs
2022, Archives of Oral BiologyCitation Excerpt :The guinea pig was selected as the experimental animal based on recent findings showing bruxism-like rhythmic jaw movements with a different pattern from natural chewing as well as cortically induced rhythmic jaw movements during sleep in guinea pigs (Kato et al., 2018; Yamada et al., 2019). Furthermore, the guinea pig is frequently used to investigate the physiology of the trigeminal motor system (Byrd, 1981; Goldberg & Tal, 1978; Pedemonte, Gambini, & Velluti, 2005). Experiments were conducted using eight male Hartley guinea pigs weighing 600–700 g. Male animals were used to avoid the confounding influences of sex differences on the functions of the amygdala (Blume et al., 2017; Premachandran, Zhao, & Arruda-Carvalho, 2020).

2009, Clinical NeurophysiologyCitation Excerpt :A third hypothesis is the effect of motor-related activities elicited by mastication. Repetitive electrical stimulation of a certain area of the cerebral cortex induces rhythmic jaw movements in many species, including monkeys (Lund and Lamarre, 1974; Huang et al., 1989), cats (Nakamura and Kubo, 1978; Iwata et al., 1985, 1990), guinea pigs (Goldberg and Tal, 1978; Nozaki et al., 1986a,b), and rabbits (Lund et al., 1984; Liu et al., 1993). Such rhythmic jaw movements with coordinated rhythmic movements of the tongue and facial organs as well as the secretion of saliva are known collecting as fictive mastication, and the cortical regions involved in these rhythmic jaw movements are termed the ‘cortical masticatory area (CMA)’ (Nakamura and Katakura, 1995; Yamada et al., 2005).

2004, Brain ResearchCitation Excerpt :In the present study, when a wooden stick was inserted between the molar teeth during the CRJMs, the TCD and SCD increased, and the jaw gape increased while the lateral excursion of the jaw decreased. These results are generally in agreement with previous studies which investigated the effects of sensory inputs in the mouth during the CRJMs in anesthetized animals [9,25,42]. Lavigne et al. reported that the TCD as well as the SCD increased with the increase in the Mass activity when a steel ball was inserted between the molar teeth during the CRJMs, and the jaw gape slightly decreased while the lateral excursion of the jaw increased because of the exaggerated swing of the mandible to the working side [25].
