i, amplitude of the single-channel current; Po, open probability; σn1; RMS noise of the open level determined with eqn (7); σn1/i, RMS noise of the open level normalized with respect to i; τof, fast open time constant; τos, slow open time constant; Af, amplitude of the fast component of the open time; As, amplitude of the slow component of the open time. The numbers in parentheses indicate the number of patches or the number of individual openings
included in the statistics.
