Brief episodes of high-frequency firing of sensory neurons, or bursts, occur in many systems, including mammalian auditory and visual systems, and are believed to signal the occurrence of particularly important stimulus features, i.e., to function as feature detectors. However, the behavioral relevance of sensory bursts has not been established in any system. Here, we show that bursts in an identified auditory interneuron of crickets reliably signal salient stimulus features and reliably predict behavioral responses. Our results thus demonstrate the close link between sensory bursts and behavior.
感觉神经元的高频放电短暂发作，即爆发，出现在包括哺乳动物听觉和视觉系统在内的许多系统中，并且被认为是特别重要的刺激特征出现的信号，即起到特征探测器的作用。然而，感觉爆发在任何系统中的行为相关性尚未得到证实。在这里，我们表明，蟋蟀一个已识别的听觉中间神经元中的爆发可靠地标志着显著的刺激特征，并可靠地预测行为反应。因此，我们的结果证明了感觉爆发与行为之间的紧密联系。
