Functional analysis of the rabbit temporomandibular joint using dynamic biplane imaging
2014, Journal of BiomechanicsCitation Excerpt :Comparing our results to previous rabbit kinematic studies showed that our study yielded similar findings. In several studies, the chewing patterns were studied by affixing a magnet to the mandible and a magnetic sensor to the skull and the voltage differences were measured (Inoue et al., 2004; Langenbach et al., 2001; Morita et al., 2008; Tominaga et al., 2000; Yamada and Haraguchi, 1995; Yamada et al., 1988, 1990). The general paths and patterns of the incisors in the vertical and horizontal directions were similar to what we observed (Fig. 8), but numerical comparison was not possible, due to the measurement techniques.
Effects of chewing and swallowing behavior on jaw opening reflex responses in freely feeding rabbits
2013, Neuroscience LettersCitation Excerpt :Before surgery, each animal was placed in a box (40 cm × 18 cm × 18 cm) with a frontal door for a period of at least 1 week, where they were trained to take chow pellets from the front of the box. The surgical procedure has been extensively described in our previous studies [1,4,5]. Briefly, animals were anesthetized with pentobarbital sodium (30–35 mg/kg body weight) administered intravenously through the marginal ear vein, supplemented with thiopental sodium (10 mg/h, iv) to maintain anesthesia at a level at which neither apparent corneal reflexes nor spontaneous eye movements occurred.
Face sensorimotor cortex neuroplasticity associated with intraoral alterations
2011, Progress in Brain ResearchCitation Excerpt :However, we did not record EMG or movement parameters during the animal's oral sensorimotor functions, so further studies are needed to determine if incisal trimming or extraction is associated with alterations in oral sensorimotor behavior. Changes in diet consistency may also be associated with altered motor behavior such as altered biting and chewing forces and different patterns of mastication (Inoue et al., 2004; Okayasu et al., 2003; Proschel and Hofmann, 1988). In contrast to the significant changes in AD or GG motor representations within face-M1 produced by dental extraction and trimming, a change in diet consistency had no significant effects.
The influence of food material properties on jaw kinematics in the primate, Cebus
2010, Archives of Oral BiologyCitation Excerpt :We hypothesized that variance in feeding sequence duration is determined primarily by variance in the number of chews in a feeding sequence rather than by variance in mean chew cycle duration.13,18,19 In mammals, harder or tougher foods elicit more cycles per chew sequence than softer foods, more cycles prior to the first swallow and more chews per swallow.13,17–20,39–42 If variance in feeding sequence duration is determined primarily by variance in the number of chews, then variance in FMPs impacting the number of chews in a feeding sequence will also impact total sequence duration.
