The femoral chordotonal organs of Decticus albifrons (Orthoptera: Tettigoniidae)—II. Function

Three Neural Groups in the Femoral Chordotonal Organ of the Cricket Gryllus Bimaculatus: Central Projections and Soma Arrangement and Displacement During Joint Flexion

“…It has been reported that partly fused scoloparia similar to those in Gryllus bimaculatus are present in another species of cricket, Acheta domesticus (Nowel et al 1995), in a tettigoniid (Theophilidis, 1986), in the weta (Matheson and Field, 1990) and in the stick insect (Füller and Ernst, 1973). In the locust, however, two scoloparia in the pro-and mesothoracic FCOs are completely separated into the distal scoloparium and proximal scoloparium and are innervated by different nerve bundles (Burns, 1974;Field and Pflüger, 1989).…”

“…It has been reported that the FCO consists of two scoloparia that are present in all the legs of the stick insect Carausius morosus (Füller and Ernst, 1973) and the tettigoniid Decticus albifrons (Theophilidis, 1986), in the pro-and mesothoracic legs of the locust Schistocerca gregaria (Burns, 1974) and in the metathoracic leg of the weta (Matheson and Field, 1990) and the cricket Acheta domesticus (Nowel et al 1995). In the locust, the neurones in the two scoloparia of the mesothoracic FCO have different central projections in the thoracic ganglion (Field and Pflüger, 1989).…”

Range fractionation in the locust metathoracic femoral chordotonal organ

“…Theophilidis (1986) has higher values for Decticus (minimum approximately 230 Hz, maximum 550 Hz). These low rates suggest that only the largest tonic spikes are being detected in extracellular records.…”

Structure of the Femoral Chordotonal Organ in the Oleander Hawkmoth, Daphnis nerii

“…It is located in the femur and monitors the femoro‐tibial (FT) joint of each leg. Composed of several closely packed neurons, FeCO encodes several aspects of the FT joint state including the angular position of tibia relative to femur, the speed and direction of the tibial movement, and the substrate vibrations transmitted via the tarsi and tibia (Burns 1974; Büschges 1994; Field and Pflüger 1989; Hofmann, Koch, and Bassler 1985; Mamiya, Gurung, and Tuthill 2018; Matheson 1990; Stein and Sauer 1999; Theophilidis 1986; Usherwood, Runion, and Campbell 1968; Zill 1985).…”
