Electrophysiology of Scorpion Peg Sensilla
We describe a modification of an existing tip-recording technique for electrophysiologically investigating short, peg-like sensory sensilla. On the mid-ventral surface of all scorpions are two appendages called pectines, which have dense fields of mechano- and chemosensory peg sensilla. One method for assessing chemoresponsiveness of these sensilla uses a tungsten electrode for extracellularly ...
متن کاملElectrophysiological analysis of synaptic interactions within peg sensilla of scorpion pectines.
Pectines are unique, midventral sensory appendages that help direct mating and food-finding behaviors in scorpions. Dense two-dimensional arrays of bimodally sensitive (chemical and mechanical) peg sensilla form the primary sensory structures on pectines. Several qualities of peg sensilla make them well suited to electrophysiological investigation, including accessibility, stability of extracel...
متن کاملAre mechanoreceptors involved in the neural circuitry of scorpion peg sensilla ?
Scorpion pectines are paired, ventral appendages that extend from their eleventh body segment. Each pecten resembles a comb with a jointed spine connecting numerous teeth. The ventral surface of each tooth contains a dense patch of truncated hairs, called peg sensilla. Morphological and electrophysiological studies have concluded that numerous chemoreceptive neurons are present in each peg whil...
