Entropy is a measure of the variability of a signal. In each neural site, the signal is registered like a sequence of 0/1 binary events: signals are encoded in bits (a). The number of occurrences of a bit in a sequence is the probability that a bit is generated, from the probability; entropy may be derived (b).
