### Re: Channel noise

Hi, I would like to propose an other approach: lets assume we divide a membrane into n parts, which are represented by random variables X_1,...,X_n - the "value" of this random variables is representing the current fluctuations (without specifying the distribution, but maybe we can assume a N(0,1) d...

### Re: Channel noise

Dear Ted, I know an stochastic approach with Markov chains does exist, but is the question answerable due to simple statistics ? If we take a look at N channels - the probability that n channels are open follows a binomial distribution Bin(n,p) - so the standard deviation is proportional to the squa...

### Channel noise

Hi guys, One knows, an ionic channel can be either open or closed - if we take a look at N channels, the probability that n channels are open needs to follow a binomial distribution.... now the standard-deviation is proportional to the square root of the considered channels -- therefore : more chann...
