We used an antiserum directed against γ-aminobutyric acid (GABA) fixed with
glutaraldehyde (Hoskins et al., Cell Tissue Res. 244: 243-252,'86) to label neurons with …

The innervation of 18 uropod and telson muscles in the crayfish has been studied in varying
detail. Some muscles display purely phasic properties (short sarcomeres, electrically …

Within the hierarchy of sensory interneurones in the crayfish, individual cells exist which
code specifically for directional components of waterborne stimuli. The caudal photoreceptor …

The uropod steering equilibrium response in crayfish is facilitated during the spontaneous
abdominal posture movement. This facilitation could also be observed when the abdominal …

In the crayfish abdomen the anterior five of six ganglia are serially homologous. The
locations and sizes of motoneuron somata of the fast and slow flexor systems have been …

1. The location of both the crayfish antennal motoneuron somata, and dendrites were
determined using a cobalt chloride backfilling technique. The cobalt technique is especially …

The ground-breaking papers of Donald Kennedy and Kimihisa Takeda (Kennedy and
Takeda, 1965b; Kennedy and Takeda, 1965a) on crustacean motor systems established a …

Using chronically implanted suction electrodes (Fig. 2), records were obtained from the tonic
abdominal flexor motor neurons of crayfish while they were undergoing various self …

The functional anatomy of the crayfish third abdominal ganglion was explored by
reconstructions from silver‐stained serial sections and by intracellular recording from units in …

Intracellular and extracellular recordings have been made from neurones of the swimmeret
system in the semi-isolated abdominal ganglion of the crayfish during rhythmic activity …
