The detailed electronic configuration of a lightweight (7 g) battery-operated portable electrical stimulator unit is described. It has proven useful for the study of the effects of chronic stimulation on skeletal muscle in small animals (i.e., the rat). The unit requires wavelengths in the infrared region for activation. This allows for remote triggering of the stimulator and permits it to function reliably even when animals are housed in rooms illuminated by fluorescent lamps. Unique to the system is the inclusion of a visual indicator of unit function (light-emitting diode), thus providing a convenient means of monitoring unit activation. The stimulator unit described has proven to be highly reliable and very useful for the study of alterations in gene expression in muscle subject to chronic use (M. Takahashi and D. A. Hood, J. Appl. Physiol. 74: 934-941, 1993).
本文描述了一款重量轻（7克）、由电池供电的便携式电刺激器的详细电子配置。事实证明，它对于研究慢性刺激对小型动物（即大鼠）骨骼肌的影响很有用。该装置需要红外区域的波长来激活。这允许对刺激器进行远程触发，并使其即使在动物饲养在荧光灯照明的房间中时也能可靠地运行。该系统的独特之处在于包含一个装置功能的视觉指示器（发光二极管），从而提供了一种监测装置激活的便捷方法。所述的刺激器已被证明高度可靠，对于研究长期使用的肌肉中基因表达的变化非常有用（高桥正明和D.A.胡德，《应用生理学杂志》74:934 - 941,1993）。
