...: a decreasing second moment of area calculated from the measured taper and the diminishing wall (cuticle) thickness. Cricket antennae recovered from a single localized perturbation quickly and with minimal to no oscillation, suggesting behavior close to critical damping (fastest return without oscillations...

... suggested that anterior and posterior body segments oscillate at different frequencies from each other. We attached accelerometer, gyroscope and magnetometer data loggers to the anterior and posterior body sections of smooth dogfish, Mustelus canis ( n =4), and released these individuals in the wild...

... of the robots was evaluated by computer simulation. We demonstrated that the group-size-dependent strategy in crickets could be generated by local interactions between robots, where the behaviour was governed by an oscillator and memory of the outcome of previous fights. Individuals or groups...

... cells. In addition, the action potential activity of unstimulated olfactory receptor neurons was examined in the presence of biogenic amines. Under constant environmental conditions, the transepithelial potential oscillated regularly with periods of 2-8 min and with a 1-25 mV peak-to-peak amplitude over...

... currents causes an increase in input resistance. Larger hyperpolarising currents cause oscillations in the membrane potential. The amplitude of the oscillations increases with current strength. Repolarisation generates brief rebound spikes of variable amplitude. Injection of small hyperpolarising currents...

...P. J. F. De Graaf; B. L. Roberts ABSTRACT Artificial oscillation imposed onto the gill arches could modify the respiratory rhythm in the carp Cyprinus carpio . The degree of modification depended upon the frequency and amplitude of the applied movement. Oscillation at frequencies close...

...-amplitude duration of about 1·5 min, was also induced, either during the K elevation or after. Given sufficient K exposure, a series of these transients occurred, with a periodicity of 3–15 min, indicating that a cellular oscillator had been activated. The delay between application of high K...
