Characterization of Subthreshold Voltage Fluctuations in Neuronal Membranes
Synaptic noise due to intense network activity can have a significant impact on the electrophysiological properties of individual neurons. This is the case for the cerebral cortex, where ongoing activity leads to strong barrages of synaptic inputs, which act as the main source of synaptic noise affecting on neuronal dynamics. Here, we characterize the subthreshold behavior of neuronal models in...
متن کاملComment on “ Characterization of Subthreshold Voltage Fluctuations in Neuronal Membranes , ” by M . Rudolph and A .
In two recent articles, Rudolph and Destexhe (2003, 2005) studied a leaky integrator model (an RC-circuit) driven by correlated (“colored”) gaussian conductance noise and Gaussian current noise. In the first article, they derived an expression for the stationary probability density of the membrane voltage; in the second, they modified this expression to cover a larger parameter regime. Here we ...

In the first paper they derived an expression for the stationary probability density of the membrane voltage; in the second paper this expression wa...

متن کاملIon Channel Fluctuations in Pure Lipid Bilayer Membranes: Control by voltage
Lipid bilayer membranes are shown to represent a dielectric barrier, which due to the thermodynamic fluctuations in membrane thickness, reversibly breaks down forming ion channels of discrete conductivity. The probability of the phenomenon is controlled by the electrostatic membrane potential (voltage) as well as by pH, pCa, surface pressure and temperature. Ion channel probability increases wi...
