摘要: The voltage‐fluctuation noise spectrum appearing across the excised urinary bladder of female Dominican toad B u f o m a r i n s during active transport sodium is identified as arising from random current fluctuations in sodium‐ion current. observed to disappear with blocked when bathed choline Ringer solution. magnitude open‐circuited and short‐circuited proportional open‐circuit taken be equal Ohmic through resistance at resting potential. short‐circuit external that must injected into drive transbladder potential zero. determined measurement frequency‐dependent impedance bladder. Interpretation spectral density according theoretical expressions for current‐fluctuation indicates are produced by correlated movement large number ions, carrying approximately 5000 electronic charges time 0.02 sec.
