Temporal summation by Pacinian corpuscles precludes entrainment at the detection threshold. 1985

C L Van Doren

For rapidly adapting mechanoreceptor afferents, entrainment is defined as a response of one spike per stimulus cycle. For Pacinian corpuscles, the entrainment threshold and psychophysical detection threshold are similar. The psychophysical threshold, however, exhibits temporal summation, which proves that the psychophysical threshold and the physiological entrainment threshold cannot be identical.

D008465	Mechanoreceptors	Cells specialized to transduce mechanical stimuli and relay that information centrally in the nervous system. Mechanoreceptor cells include the INNER EAR hair cells, which mediate hearing and balance, and the various somatosensory receptors, often with non-neural accessory structures.

D010141	Pacinian Corpuscles	Rapidly adapting mechanoreceptors found in subcutaneous tissue beneath both hairy and glabrous skin. Pacinian corpuscles contain an afferent nerve fiber surrounded by a capsule with multiple concentric layers. They have large receptive fields and are most sensitive to high-frequency stimuli, such as vibration.	Pacinian Corpuscle,Corpuscle, Pacinian,Corpuscles, Pacinian
