1. 当猴子在进行一项延迟匹配样本的视觉记忆任务时，研究者在双侧内侧颞叶区域施加了一到四个0.2毫秒、100赫兹的电流脉冲。短暂的电刺激被用作探针，以确定在20或50毫秒的样品呈现过程中，什么时候干扰最严重。2. 在样本图像出现后约200毫秒内的刺激严重扰乱了动物随后识别图像的能力。在其他时间同样的刺激则没有。3. 因此，在编码过程中，植入内侧颞叶电极可以访问的处理，似乎只发生在与接收感觉输入相关的短暂间隔中。
1. A burst of from one to four current pulses of 0.2 ms at 100 Hz was administered bilaterally to medial temporal lobe areas while monkeys worked in a delayed matching-to-sample visual memory task. The brief electrical stimulation was used as a probe to determine when, around the 20 or 50 ms sample presentation, the disruption was most severe. 2. Stimulation within about 200 ms of the sample image onset severely perturbed the animals' ability subsequently to recognize that image. Identical stimulation at other times did not. 3. Thus, the processing during encoding, that is accessible to the implanted medial temporal lobe electrodes, appears to occur only in a brief interval associated with receipt of the sensory input.
