This paper describes a newly designed vector stimulator which can independently stimulate both sides of an animal's canine or incisor teeth to analyse the functional properties of periodontal mechanosensitive (PM) units. The stimulator was designed so as to control and stimulus direction (0 degree-360 degrees) and intensity (0-0.98 N) within the horizontal plane (vector), the rate of application (0.049-490 N/s), and the duration (0-10 s). The stimulator is composed of electromagnetic drivers, a trapezoid-wave generator, and a stimulus monitor. The former is adopted from conventional pen drivers, and the latter two are composed of operational amplifier circuits. The vector stimulator was utilized to apply a stimulus force to the canine teeth of a cat, and the responses of the PM units were recorded in the somatosensory cerebral cortex.
本文描述了一种新设计的矢量刺激器，它可以独立刺激动物犬齿或门牙的两侧，以分析牙周机械敏感（PM）单元的功能特性。该刺激器的设计目的是在水平面（矢量）内控制刺激方向（0度 - 360度）和强度（0 - 0.98 N）、施加速率（0.049 - 490 N/s）以及持续时间（0 - 10 s）。该刺激器由电磁驱动器、梯形波发生器和刺激监测器组成。前者采用传统的笔式驱动器，后两者由运算放大器电路组成。利用该矢量刺激器对猫的犬齿施加刺激力，并在体感大脑皮层记录PM单元的反应。
