Statistical properties of single sodium channels
Single channel currents were obtained from voltage-activated sodium channels in outside-out patches of tissue-cultured GH3 cells, a clonal line from rat pituitary gland. In membrane patches where the probability of overlapping openings was low, the open time histograms were well fit by a single exponential. Most analysis was done on a patch with exactly one channel. We found no evidence for mul...
متن کاملStatistical Properties of Correlation on WSSUS Channels
To properly characterize the frequency and time selectivity of the fading channel, there several models used to simulate the channel, most of them based in the Jake’s simulator. In this work the second order statistics of this simulator are compared to actual measurements. The second-order statistics level crossing rate (LCR) and average duration of fading (ADF) of a random process transmits us...
متن کاملInactivation viewed through single sodium channels
Recordings of the sodium current in tissue-cultured GH3 cells show that the rate of inactivation in whole cell and averaged single channel records is voltage dependent: tau h varied e-fold/approximately 26 mV. The source of this voltage dependence was investigated by examining the voltage dependence of individual rate constants, estimated by maximum likelihood analysis of single channel records...
متن کاملKinetic properties of single sodium channels in rat heart and rat brain
Single Na channel currents were compared in ventricular myocytes and cortical neurons of neonatal rats using the gigaseal patch-clamp method to determine whether tissue-specific differences in gating can be detected at the single-channel level. Single-channel currents were recorded in cell-attached and excised membrane patches at test potentials of -70 to -20 mV and at 9-11 degrees C. In both c...
متن کاملElementary functional properties of single HCN2 channels.
Hyperpolarization-activated cyclic-nucleotide-gated (HCN) channels are tetramers that evoke rhythmic electrical activity in specialized neurons and cardiac cells. These channels are activated by hyperpolarizing voltage, and the second messenger cAMP can further enhance the activation. Despite the physiological importance of HCN channels, their elementary functional properties are still unclear....
