Webhuman psychometric function for discriminating grating orientation. Human discrimination begins to rise above chance behavior when gaps and bars are 0.5mm wide and reaches threshold when they are about 1.0mm wide [9,10]. The selective sensitivity for edges and bars illustrated in Figure 1 arises from the Merkel receptor’s selective WebTherefore, the functions of Piezo2 in the Merkel cell–neurite complexes seemed to be centred in the cells rather than in the nerve terminals. Our results are in good agreement with data demonstrating that Merkel cells are mechanosensitive cells (Maricich et al. 2009) and function in touch transduction via Piezo2 (Woo et al. 2014).
