Abstract

Locust wing stretch receptor is known to exhibit firing frequency adaptation when the forewing is lifted to a constant position. However, during flight, the wing periodically moves and the receptor’s response properties are in this dynamic mode unknown. We recorded extracellularly the response from the Locusta migratoria forewing stretch receptor while the wing was periodically lifted and found that the adaptation of the stretch receptor is expressed in a dynamic mode as well; however, this adaptation is weaker than in the static mode.
