Control of stepping velocity in the stick insect Carausius morosus.
We performed electrophysiological and behavioral experiments in single-leg preparations and intact animals of the stick insect Carausius morosus to understand mechanisms underlying the control of walking speed. At the level of the single leg, we found no significant correlation between stepping velocity and spike frequency of motor neurons (MNs) other than the previously shown modification in f...

متن کاملHormonal control of the malpighian tubules of the stick insect, Carausius morosus.
Factors have been isolated from the central nervous system of the stick insect, Carausius morosus, which affect the rate of secretion of the Malpighian tubules (Gersch et al. i960; Unger, 1965; Vietinghoff, 1967), but it has not yet been shown that these factors are of physiological importance in vivo. There is, however, an accumulation of stainable material in the corpora cardiaca of Carausius...
متن کاملIdentification of multiple peptides homologous to cockroach and cricket allatostatins in the stick insect Carausius morosus.
Eighteen peptides were isolated from brain extracts of the stick insect Carausius morosus. The peptides were purified in four steps by high-performance liquid chromatography, monitored by their ability to inhibit juvenile hormone biosynthesis by corpora allata of the cricket Gryllus bimaculatus in vitro, and chemically characterised by Edman degradation and mass spectrometry. We obtained comple...
متن کاملCalcium Action Potentials in the Skeletal Muscle Fibres of the Stick Insect Carausius Morosus
The ionic requirements for the generation of action potentials in the ventral longitudinal muscle fibres of the stick insect, Carausius morosus, were investigated. Ca-free Ringer rapidly and reversibly abolished the action potential. In the presence of tetraethylammonium (TEA) ions (to suppress outward currents) the overshoot of the action potential changed 26 mV for a 10-fold change in [Ca]0. ...
