Distribution of cluster durations from one patch. A cluster occurs when a single AChR spontaneously recovers from desensitization, and a cluster ends when that receptor again becomes desensitized. Three example clusters are shown (inward current is down). The distribution of cluster durations is described by a single exponential with a time constant of 513 ms. In this patch, there were 63 clusters longer than 100 ms in duration and the mean probability of being open in a cluster was 0.47. The desensitization rate constant, (τ_c P _o)⁻¹, was 3.9 s⁻¹ (−100 mV; 20 μM ACh; 115 mM NaCl).
