Abstract(in English) | The energy thresholds of the sensory cell of the cricket wind receptor were determined to be at the thermal noise level k_BT(4×10^<-21> J at 300 °K). The determination was based on a laser-Doppler velocimetry of the receptor hair and the Stokes'theory for viscous force. The mechanoreceptor exhibits fluctuations in spike timing to near-threshold stimuli. Simultaneous double repordings revealed independency of the fluctuations between cells. The cells employ the internal thermal noise as the seed of randomness for a non-correlated signal sampling. The thermal noise paradoxically enhances the detection of weak signal below the threshold. |
