Most electrophysiological studies of sound reception have been undertaken with sharpened metal electrodes inserted into Johnston's organ. The receptors potentials that are elicited in Johnston's organ by vibration of the antennal flagellum, when recorded via an extracellular electrode, are sinusoidal in form but occur at twice the frequency of the acoustic stimulus. This phenomenon has been termed frequency doubling. idomal_namespace sensory coupling nervous system process transduction of receptor potential IDOMAL:0002222 IDOMAL:0002222 Mechanical deformation of the dendritic membrane, producing receptor potentials.
