Abstract
1. 1. Percussion or electrical stimulation of the carapace in T graeca elicited responses at the ipsilateral cord dorsum. The segmental levels of inflow were identified by mapping and dorsal rhizotomy. 2. 2. The waveform properties of the cord dorsum potentials resembled those associated with cutaneous stimulation. 3. 3. The effects of local stimulation and local anaesthesia indicate that a proportion of nerve endings in the carapace are present in the superficial layers of the thecal bone. 4. 4. Conduction velocity of afferents from the carapace was 14.5 m/sec (mean) at 23–25°C in the ipsilateral dorsal tract and therefore in the upper range for the population of tract fibres.
