A fully automated, 10-channel gustometer for use with nonhuman primates is described. The system, constructed primarily from commercially available components, includes an intelligence panel (containing sample spout, reward spout, and two operant response keys) that attaches to the door of a standard primate cage. The novel feature of the gustometer is a sample delivery spout that can be flushed, rinsed, and refilled within a specially designed rinsing chamber. All wetted surfaces of the gustometer are either Teflon, glass, or stainless steel. Flame photometric analysis confirmed the absence of cross-contamination between trials. Behavioral data collected from one rhesus monkey using a shock-suppression procedure demonstrates the detection threshold for sodium chloride. Improvements to the design, including the addition of pressurized sample delivery triggered by a lickometer circuit, are discussed.
描述了一种用于非人灵长类动物的全自动10通道味觉计。该系统主要由市售部件构成，包括一个智能面板（包含样品喷嘴、奖励喷嘴和两个操作性反应键），它可连接到标准灵长类动物笼的门上。味觉计的新颖之处在于其样品输送喷嘴，它能在一个专门设计的冲洗室内进行冲洗、漂洗和重新填充。味觉计所有湿润表面均为聚四氟乙烯、玻璃或不锈钢材质。火焰光度分析证实了各试验之间不存在交叉污染。使用电击抑制程序从一只恒河猴收集的行为数据表明了氯化钠的检测阈值。文中还讨论了对该设计的改进，包括增加由舔舐计电路触发的加压样品输送。
