..., through identification of sound radiating areas and their properties. For well-grounded comparisons, homologies in wing venation (and associated areas) of grigs and bush crickets are re-evaluated. Then, using direct evidence, this study confirms the mirror cell, in association with two other areas (termed...

...J. P. C. DUMONT; J. J. WINE 1. We describe the phasic neuromuscular system of the crayfish telson and establish its homology with the abdominal flexor system that provides the powerstroke for tailflip escape responses. 2. Three paired phasic telson muscles are innervated by 11 paired neurones which...

...J. P. C. DUMONT; J. J. WINE 1. The telson and sixth ganglion of the crayfish contain a fast flexor system that is homologous to that found in anterior segments, but doubled (Dumont & Wine, 1986 a ). In this paper we document differences in connections to the motor giants (MoGs) in the telson...
