Receptive field sizes and neuronal encoding bandwidth are constrained by axonal conduction delays

Correlation of stimulus driven response properties and receptor position.
r-values are the Pearson correlation coefficients, p-values are Bonferroni corrected. Dashed thin line shows the mean and gray areas the standard deviation estimated in bins of 10% width.A: Response modulation of the across-trial average firing rate (Eq 4) in response to frozen white noise amplitude modulations. Please note that these stimuli were only presented to a subset of 39 neurons which could be recorded sufficiently long to allow for position estimation and stimulation with white noise stimuli and were stimulated with the same stimulus intensity (10% contrast). B: response variability, i.e. the across-trial standard deviation of the firing rate (Eq 5). C, D: lower and upper -3 dB cutoff frequencies of the transfer function. E: peak gain of transfer function. F: Mutual information between responses and the stimulus estimated from the stimulus response coherence spectrum.
