Abstract
Electrophysiology has considerable potential for evaluating the responses of individual nematodes to semiochemicals. Sensory response can be quantified, electrical activity before, during and after stimulation can be compared and the occurrence of aspects such as sensory adaptation can be demonstrated. Research using the electrophysiology system to compare extracellular recordings of the responses of the cephalic region of Globodera rostochiensis and G. pallida to various compounds is discussed. The use of larger nematodes, such as the avian nematode Syngamus trachea, has enabled direct recordings to be obtained from individual sensilla, the cephalic papillae and the amphid. Electrophysiological techniques oer the opportunity to determine nematode responses in detail and to examine the function and mode of action of nematode sensilla for a more complete understanding of nematode sensory perception.
