| Outline of Final Research Achievements |
The purpose of this study is to clarify the relationship between jaw movement and salivary secretion occurring upon electrical stimulation two cortical masticatory areas in rats.
In this study, jaw movement and submandibular salivary secretion were recorded at the same time when two different cortical masticatory areas (A-area, P-area) were stimulated electrically. As a result, it became clear that P-area stimulation induced vigorous salivary secretion and rhythmical jaw movements resembling masticatory movements. In addition, salivary flow persisted even after minimizing jaw movements by curarization. From these, salivary secretion not only occur reflexively by oral sensation caused by jaw movement, it became clear that it is also controlled to the central.
