Detecting and Estimating Signals in Noisy Cable Structures, Ⅱ: Information Theoretical Analysis

摘要

This is the second in a series of articles that seek to recast classical single- neuron biophysics in information-theoretical terms. Classical cable the- ory focuses on analyzing the voltage or current attenuation of a synaptic signal as it propagates from its dendritic input location to the spike initi- ation zone. On the other hand, we are interested in analyzing the amount of information lost about the signal in this process due to the presence of various noise sources distributed throughout the neuronal membrane.
