Summary
A new sensory system, in the abdomen of the cricketAcheta domesticus, is described. It consists of hair-like receptors, which we have called ‘bristles’, distributed on the cercus and abdomen. The sensory neurons, innervating bristles of a wide variety of shapes and sizes, project to a common area of the terminal abdominal ganglion. This region is distinct from the area called the cereal glomerulus which receives input from other receptor types.
Three interneurons, whose dendrites are located exclusively in the projection area of bristle sensory neurons, are then described. These interneurons respond to tactile stimuli of the cercus and abdomen, but not to infrasound or to body orientation as do previously described interneurons. Based on the anatomical segregation of the afferents and interneurons, as well as the functional distinction from previously described cereal sensory systems, it is becoming clear that the cereal system is a multimodal sensory system.
