无脊椎动物感觉器官的一个共同特征是感觉神经元的细胞体位于周围，靠近刺激接收部位。对于某些无脊椎动物门，已知感觉细胞在中枢神经系统（CNS）内有其胞体的例子，但对于昆虫还没有已知的例子。在这份报告中，我们描述了蝗虫胸部的本体感受器官，它由一个弹性股，提供了一小群感觉神经元的终端分支。这些神经元的胞体不位于外周，而是位于第三胸神经节内。我们的研究结果表明，昆虫神经节中至少有一小部分细胞体可能属于感觉神经元，而不是运动神经元、中间神经元或神经分泌细胞。
A common feature of invertebrate sense organs is that the cell bodies of the sensory neurones are located in the periphery, close to the site of stimulus reception. For some phyla of invertebrates examples are known where sensory cells have their somata inside the central nervous system (CNS), but none are yet known for the insects. In this report we describe a proprioceptive organ in the locust thorax that consists of an elastic strand that is supplied with terminal branches of a small group of sensory neurones. The somata of these neurones are not located in the periphery, but inside the third thoracic ganglion. Our findings indicate that at least a small number of cell bodies in insect ganglia may belong to sensory neurones, rather than to motoneurones, interneurones or neurosecretory cells.
