蟋蟀通过位于前腿上的耳朵接收来自环境的听觉信息。上行中间神经元将听觉活动转发到大脑，大脑拥有一个模式识别网络，用于对同种呼唤歌曲进行趋声性，并控制对高频声音脉冲的负趋声性。然而，控制这些行为的下行脑神经元还没有被确定。我们描述了一个下降的神经元的反应与树枝状的模式，符合环状听觉神经元在大脑中形成的轴突树枝状的上升和本地interneurons，表明其密切联系的听觉处理。这种中间神经元的尖峰活动发生在短的潜伏期内，以调用歌曲模式，神经元复制声音脉冲模式。神经元优先响应短的声音脉冲，但它的活动似乎是独立的呼叫歌曲模式识别过程。它还接收响应于高频脉冲的较弱突触输入，这可能有助于其短延迟尖峰响应。这种中间神经元可能是神经系统从听觉到运动的转换中的关键部分，并有助于板球听觉行为的运动控制。
Crickets receive auditory information from their environment via ears located on the front legs. Ascending interneurons forward auditory activity to the brain, which houses a pattern recognition network for phonotaxis to conspecific calling songs and which controls negative phonotaxis to high-frequency sound pulses. Descending brain neurons, however, which are clearly involved in controlling these behaviors, have not yet been identified. We describe a descending auditory-responsive brain neuron with an arborization pattern that coincides with the ring-like auditory neuropil in the brain formed by the axonal arborizations of ascending and local interneurons, indicating its close link to auditory processing. Spiking activity of this interneuron occurs with a short latency to calling song patterns and the neuron copies the sound pulse pattern. The neuron preferentially responds to short sound pulses, but its activity appears to be independent of the calling song pattern recognition process. It also receives a weaker synaptic input in response to high-frequency pulses, which may contribute to its short latency spiking responses. This interneuron could be a crucial part in the auditory-to-motor transformation of the nervous system and contribute to the motor control of cricket auditory behavior.
