The crustacean swimmeret system includes a distributed set of local circuits that individually
control movements of one jointed limb. These modular local circuits occur in pairs in each …

The central nervous system of crayfish consists of a chain of segmental ganglia that are
linked by cables of intersegmental axons. Each ganglion contains a highly‐ordered core of …

Normal locomotion in arthropods and vertebrates is a complex behavior, and the neural
mechanisms that coordinate their limbs during locomotion at different speeds are unknown …

brain–The ventral nerve cord–Motor systems. Non–Malacostraca–Remipedia …

During forward swimming, motor neurons that innervate each crayfish swimmeret fire
periodic coordinated bursts of impulses. These bursts occur simultaneously in neurons that …

Coordination of limb movements: three types of intersegmental interneurons in the
swimmeret system and their responses to changes in excitation. During forward locomotion …

The motor pattern that drives coordinated movements of swimmerets in different segments
during forward swimming characteristically begins with a power-stroke by the most posterior …

During normal forward swimming, the swimmerets on neighboring segments of the crayfish
abdomen make periodic power-stroke movements that have a characteristic intersegmental …

Swimmerets are limbs on several segments of the crayfish abdomen that are used for
forward swimming and other behaviors. We present evidence that the functional modules …

Swimmerets move periodically through a cycle of power‐strokes and return‐strokes.
Swimmerets on neighboring segments differ in phase by~ 25%, and maintain this difference …
