Patterned Activity of Co-Ordinated Motor Units, Studied in Flying Locusts

摘要: 1. A brief survey of the locust flight system is presented as background for this and future studies. Included are descriptions wing movements, aerodynamic parameters pertinent muscle anatomy physiology. 2. procedure has been designed which makes it possible to study a complex locomotory pattern in terms activities single nervous muscular units, case during normal locusts. 3. We have found detailed repetitive precisely correlated with movements. Fig. 24 shows flight. Variations details also significant variation 4. During average most motor units fire time per stroke. In low-powered numerous inactive. With increase power additional recruited active ones may twice or more specific phase wingstroke. 5. Increase wingstroke frequency number earlier onset activity so that movements braked at top bottom by well other restoring forces. 6. Lift controlled changes twisting mainly due two-unit each wing, subalar muscle.
