A method for measuring evoked cortical potentials to acoustic stimuli through the intact dura mater of the guinea pig without computer averaging studied. After exposure of the dura overlying the auditory cortex on the left side, thresholds to acoustic stimuli presented to the right ear were determined with a double tipped silver electrode by visual detection on an oscilloscope. The thresholds obtained are compared with other methods of determining audibility levels in the guinea pig. With relatively simple instrumentation, this method provides rapid and accurate determination of the audibility curve.
一种通过豚鼠完整硬脑膜测量对听觉刺激诱发的皮质电位的方法，且未进行计算机平均处理的研究。在暴露左侧听觉皮质上方的硬脑膜后，使用双尖端银电极通过示波器上的视觉检测来确定右耳对听觉刺激的阈值。将获得的阈值与其他确定豚鼠听力水平的方法进行比较。使用相对简单的仪器，该方法可快速准确地确定听力曲线。
