[Functional connections between symmetrical segemental systems for controlling the claw muscles of the crayfish Astacus leptodactylus].
Studies have been made on functional connections between symmetric neuronal ensembles in the 1st thoracal ganglion realizing segmentary control of muscles in the claw dactylopodite. During moderate adequate stimulation of the receptive field, symmetric ensembles of efferent neurons operate independently from each other. Intensive stimulation of the receptive field results in the reflex dactylopodite abduction and in associated excitation of the symmetric contralateral group of corresponding neurons. Interaction of the symmetric ensembles is realized on both the segmentary and supersegmentary levels.
