Efficient population coding depends on stimulus convergence and source of noise
Fig 7
The tuning of auditory nerve fibers (ANFs) match predictions from optimal coding.
A. The sigmoidal function that we use to fit ANFs tuning curves. Spontaneous firing rate (r), maximal firing rate (rm), firing threshold (θ), and the dynamic range (σ) are labelled on the curve. B. An example showing original data from ref. [8] and fitted tuning curves. These two tuning curves come from the same mouse. C. Optimal configuration (cyan dots) in the contour plot of mutual information. Black dot denotes the fitted thresholds from the data. D. Optimal configuration (cyan dots) in the contour plot of average firing rate. Black dot denotes the fitted thresholds from the data.
