Abstract

Summary

1.
The rumination pattern has been studied in three goats before and after ablation of the orbito-frontal lobes of the cerebral cortex.
2.
The animals were able to ruminate within a few hours of the cortical ablation and devoted about the same amount of time in ruminating in a day as normal animals.
3.
The rumination cycle length shows an obvious irregularity following lobectomy. This irregularity of rumination cycle length is synchronised with an irregularity of reticuloruminal contractions.
4.
Following lobectomy a variation in jaw movements was apparent during remastication; this disfunction may have been due to the very fluid nature of the regurgitatied food mass which was noticeable at this time.
5.
The part played by the cerebrum in controlling the many and varied reflexes associated with rumination is discussed.

山羊眼眶额叶脑皮质消融后反刍障碍的研究

Summary1。研究了3只山羊在眼眶额叶脑皮质消融前后的反刍模式。这些动物在皮质消融后的几个小时内就能反刍，而且每天反刍的时间与正常动物差不多。肺叶切除术后反刍周期长度明显不规则。这种反刍周期长度的不规则性与网状室收缩的不规则性是同步的。肺叶切除术后，在再咀嚼过程中颌骨运动的变化是明显的;这种功能障碍可能是由于反刍食物团的液体性质，这在当时是明显的。讨论了大脑在控制与反刍相关的多种反射中所起的作用。
