Information-theoretic analyses of neural data to minimize the effect of researchers’ assumptions in predictive coding studies

Information dynamics of inter-spike intervals (ISI).
Predictability of the RGC spike train, measured by lAIS, was highest for spikes with the most frequent preceding ISI. Information transfer across the synapse, measured by lTE, was also highest for RGC spikes with the most frequent preceding ISI. While predictability was high for relayed and non-relayed RGC spikes, information transfer was only high for relayed spikes. A Distribution of ISI pooled over all cell pairs (maximum at 2 ms). B Distribution of ISI for relayed RGC spikes, pooled over all cell pairs (maximum at 2 ms). C Mean lAIS at RGC spike as a function of the preceding ISI (maximum at ISI = 3 ms, dashed vertical line, shaded area indicates ±1SD); D Mean lTE at RGC spike by preceding ISI (maximum at ISI = 2 ms, grey vertical line, shaded area indicates ±1SD); E Mean lAIS at relayed (dotted line) and non-relayed (dashed line) RGC spikes as functions of the preceding ISI (maxima at ISI = 3 ms for relayed spikes, dotted vertical line, and at ISI = 3 ms for non-relayed spikes, dashed vertical line, shaded area indicates ±1SD); F Mean lTE at relayed (dotted line) and non-relayed (dashed line) RGC spikes as functions of the preceding ISI (maxima at ISI = 2 ms for relayed spikes, dotted vertical line, and at ISI = 38 ms for non-relayed spikes, dashed vertical line, shaded area indicates ±1SD).
