Receptive field sizes and neuronal encoding bandwidth are constrained by axonal conduction delays
Fig 9
Information filtering by conduction delays is stronger than by synaptic filtering.
Comparison of the effects of conduction delays (x-axis) and synaptic transfer (y-axis) on the information content of the population response (color code). Dashed black line is the identity line. Area between horizontal dashed lines depicts the standard deviations (σkernel) of the fast and slow EPSP components as reported for the P-unit to pyramidal cell synapses [70]. Vertical dashed lines enclose the range of conduction delays that can be expected for pyramidal neurons in the lateral segment of the electrosensory lateral line lobe [39] considering the 2σ or 4σ receptive field sizes. The data shown here assumes a population size of 16 cells.
