WitrynaDOI: 10.1126/science.144.3618.554 Abstract Two determinants of adaptation in a mechanoreceptor (Pacinian corpuscle) are described. Both are filters of non-transients. One, a mechanical filter, prevents static components of the mechanical stimulus from reaching the transducer element (nerve ending). WitrynaA two-stage mechanotransduction model of its near threshold Vibrotactile (VT) sensitivity valid over 10 Hz to a few kHz is described and can be extended to simulate the neural response of a group of PCs.
