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

Correlation of baseline 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: Baseline firing rates estimated with only the unperturbed fish’s field present. Inset: In this study 84 p-type electroreceptor afferents were recorded. The blue histogram in the inset shows the distribution of receptor positions along the rostro-caudal body axis expressed relative to the total body length. The cumulative (red line) indicates that three fourths of the recorded cells were recorded in the frontal third of the body. Due to the recording location cells in the frontal 20% of the body could not be recorded. B: Coefficient of variation of the interspike interval distribution (CVISI) during baseline activity. C: Fraction of action potentials observed as part of action potential bursts as previously defined [51]. D: Vector strength quantifying the phase-locking to the EOD.
