本研究的目的是确定体感皮层 (SI) 在控制进食过程中口面部运动中的作用。我们确定了猫 SI 的口周和舌头投射区域，并通过注射红藻氨酸破坏了一个区域的细胞。然后对口面部行为的影响进行了 4-6 周的研究。口周区域单侧病变的猫（PL-猫）在早期阶段会从口腔的对侧掉落食物。在整个实验期间，观察到咀嚼运动期间对侧胡须无法竖立，并且咀嚼开始延迟。此外，在后期，PL-猫表现出咀嚼和食物摄入时间的延长，伴随着吞咽次数和咀嚼周期的增加。舌区单侧病变的猫（TL-猫）早期表现出咀嚼期延长，并伴有吞咽次数和咀嚼周期的增加。 TL-猫没有表现出进食时间的延长和对侧胡须竖立的失败。 PL-和TL-猫的咀嚼和吞咽节律均正常。
The purpose of this study was to determine the role of somatosensory cortex (SI) in the control of orofacial movements during eating. We identified perioral and tongue projection regions of the cat SI and destroyed cells in one region by injecting kainic acid. The effects on orofacial behavior were then studied over a period of 4-6 weeks. Cats with unilateral lesions in the perioral region (PL-cats) dropped food from the contralateral side of the mouth in the early phase. Failure in erection of the contralateral whisker hairs during masticatory movements and delay of the masticatory start were observed throughout the experimental period. Furthermore, in the late phase, PL-cats showed prolongations of the masticatory and food intake periods, which were accompanied by the increase in the number of swallows and chewing cycles. Cats with unilateral lesions in the tongue region (TL-cats) showed the prolongation of the masticatory period in the early phase, which was accompanied by the increase in the number of swallows and chewing cycles. TL-cats did not show the prolongation of the food intake period and failure in erection of the contralateral whisker hairs. In both PL- and TL-cats, masticatory and swallowing rhythms were normal.
