An intact cricket walks mostly with a tripod gait, similar to other insects. The motor control center of the leg movements is located in the thoracic ganglia. In this study, we investigated the walking gait patterns of the crickets whose ventral nerve cords were surgically cut to gain an understanding of how the descending signals from the head ganglia and ascending signals from the abdominal nervous system into the thoracic ganglia mediate the initiation and coordination of the walking gait pattern. Crickets whose paired connectives between the brain and subesophageal ganglion (SEG) (circumesophageal connectives) were cut exhibited a tripod gait pattern. However, when one side of the circumesophageal connectives was cut, the crickets continued to turn in the opposite direction to the connective cut. Crickets whose paired connectives between the SEG and prothoracic ganglion were cut did not walk, whereas the crickets exhibited an ordinal tripod gait pattern when one side of the connectives was intact. Crickets whose paired connectives between the metathoracic ganglion and abdominal ganglia were cut initiated walking, although the gait was not a coordinated tripod pattern, whereas the crickets exhibited a tripod gait when one side of the connectives was intact. These results suggest that the brain plays an inhibitory role in initiating leg movements and that both the descending signals from the head ganglia and the ascending signals from the abdominal nervous system are important in initiating and coordinating insect walking gait patterns.<\/jats:p>","DOI":"10.3389\/frobt.2021.625094","type":"journal-article","created":{"date-parts":[[2021,3,29]],"date-time":"2021-03-29T00:38:08Z","timestamp":1616978288000},"update-policy":"https:\/\/2.zoppoz.workers.dev:443\/https\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":7,"title":["Descending and Ascending Signals That Maintain Rhythmic Walking Pattern in Crickets"],"prefix":"10.3389","volume":"8","author":[{"given":"Keisuke","family":"Naniwa","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hitoshi","family":"Aonuma","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2021,3,29]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"130","DOI":"10.1163\/156853961X00042","article-title":"Aggressiveness, territoriality, and sexual behavior in field crickets (Orthoptera: Gryllidae)","volume":"17","author":"Alexander","year":"1961","journal-title":"Behaviour"},{"key":"B2","doi-asserted-by":"publisher","first-page":"jeb228874","DOI":"10.1242\/jeb.228874","article-title":"Serotonergic control in initiating defensive responses to unexpected tactile stimuli in the trap-jaw ant Odontomachus kuroiwae","volume":"223","author":"Aonuma","year":"2020","journal-title":"J.
