On the basis of comparisons between total cell counts and cell counts of cobalt backfills of
all roots and connectives leaving the ganglion, we estimate that 38–50% of the …

Not only nonspiking local interneurons but also spiking local interneurons in the terminal
abdominal ganglion of the crayfish (Procambarus clarkii Girard) contribute to form the motor …

Cobalt backfills were used to demonstrate a population of approximately 50 paired
interneurons in the 6th abdominal ganglion of the crayfish, Procambarus clarkii. Intracellular …

Responses of ascending interneurons from the caudal ganglion of crayfish have been
recorded from single units isolated by dissection from the ventral nerve cord; in addition …

Intracellular recording and dye injection was used to investigate the flexion‐evoking
interneurons in the isolated abdominal nerve cord of the crayfish, Procambarus clarkii. The …

An intracellular search was undertaken in an effort to locate and characterize the elements
involved in command-driven positional behavior in the isolated abdominal nerve cord of the …

Unilateral local nonspiking interneurons in the terminal (sixth) abdominal ganglion of
crayfish (Procambarus clarkii Girard) can be classified into two major groups of PL and AL …

Many behavior patterns of the crayfish involve the positioning of the abdomen by the tonic
motor system. Movements and positionings of the swimmerets are coordinated with these …

1. Electrical stimulation of afferents innervating an exopodite causes a closing pattern of
activity in the uropod motor neurons. In this reflex two distinct types of nonspiking local …

The processing of proprioceptive information from the exopodite-endopodite chordotonal
organ in the tailfan of the crayfish Procambarus clarkii (Girard) is described. The chordotonal …
