我们研究了相关的神经元放电率变异性的准确性，编码量可以从神经元的人口中提取的影响。与普遍认为的相反，神经元放电率的变异性的相关性一般不会限制通过使用大量编码神经元提供的编码准确性的增加。此外，在某些情况下，但不是所有情况下，相关性提高了人口代码的准确性。
We study the impact of correlated neuronal firing rate variability on the accuracy with which an encoded quantity can be extracted from a population of neurons. Contrary to widespread belief, correlations in the variabilities of neuronal firing rates do not, in general, limit the increase in coding accuracy provided by using large populations of encoding neurons. Furthermore, in some cases, but not all, correlations improve the accuracy of a population code.
