...Eize J. Stamhuis; John J. Videler ABSTRACT The morphology of the pleopods, uropods and telson of the tube-dwelling shrimp Callianassa subterranea have been studied using dissection microscopy and scanning electron microscopy. The kinematics of these appendages were examined by motion analysis...

...Maki Murayama; Masakazu Takahata ABSTRACT One of the postural reflexes of crayfish, the uropod steering response, is elicited by specific sensory inputs while the animal is walking. It is not elicited, however, by the same inputs when the animal is at rest. To clarify the neuronal mechanisms...

...Maki Murayama; Masakazu Takahata ABSTRACT The synaptic activities underlying the uropod steering behaviour of crayfish evoked by tilting the substratum beneath the legs have been studied intracellularly in unanaesthetized animals standing or walking on a treadmill. The uropod motoneurones showed...

...Laurence H. Field; Philip L. Newland; Mituhiko Hisada ABSTRACT Three new chordotonal organs are described: APCO for the abdominal-proto-podite joint, PExCO for the protopodite-exopodite joint and PEnCO for the protopodite-endopodite joint of the crayfish uropod. The PEnCO is a distinct strand...
