1.对于蟋蟀Tettigonia viridissima的便携式记录单元的构建，使长期的细胞外记录的单个和确定的听觉神经细胞在该领域。因此，可以在动物的自然环境中研究声音接收和定向听觉的各个方面。2.在两个例子中证明了该技术的适用性。在草原栖息地发现了40-50米的显着听觉距离;在密集的沼泽地，这些距离减少了约20米（图2）。一旦刺激是阈上的，歌曲的总体时间结构就被很好地编码在欧米茄神经元的活动中，即使在反射和散射的植被中也是如此。3.通过记录一对方向敏感的中间神经元在现场的活动，我们有直接的实验证据表明，方向信息是在显着的通信距离提供的，并且强烈依赖于发送者和接收者之间的空间配置（图3）。
1. For the bushcricket Tettigonia viridissima a portable recording unit was constructed which enabled long-term extracellular recordings of single and identified auditory nerve cells in the field. Thus, aspects of sound reception and of directional hearing could be studied in the animal''s natural environment. 2. The applicability of the technique is demonstrated in two examples. Remarkable hearing distances of 40-50 m were found in a grassland habitat; in denser bushland, these distances are reduced by about 20 m (Fig. 2). Once the stimulus is suprathreshold, the gross temporal structure of the song is well encoded in the activity of the omega-neuron even within a reflecting and scattering vegetation. 3. By recording the activity of a pair of directionally-sensitive interneurons in the field we have direct experimental evidence that directional information is provided at remarkable communication distances and strongly depends on the spatial configuration between sender and receiver (Fig. 3).
