Synaptic transmission in the 7th abdominal ganglion of the scorpion, Heterometrus fulvipes (C. Koch).
Electrical recordings made from the peripheral nerves of the 7th abdominal ganglion in the scorpion, H. fulvipes showed pronounced activity on ipsilateral stimulation of the connective and minimum activity on the contralateral side. Measurement of conduction velocities and synaptic delays indicated that ipsilateral pathways are probably monosynaptic and excitatory, while contralateral pathways might be polysynaptic and inhibitory. The nature of transmission has been suggested to be chemical.
