Information Theoretic Approach to the Study of Auditory Coding
... We further show that the redundancies in IC are correlated with the frequency characterization of the cells; namely, redundant pairs tend to share a similar best-frequency. This effect is much weaker in MGB and AI, suggesting that even the low redundancy in these stations is not due to similar frequ ...
