Response determinism of event-based input encodings with varying input history.

(A) Ratios of response distribution categories as the number of input events in the input encoding, n, increases shows a general increase in determinism when more inputs are known. (B) Phase transition diagrams showing the transitions between response distribution categories for B.1) high values of n (n in 15, 16, … 20), (B.2) medium values of n (n in 9, 10, … 14), and (B.3) low values of n (n in 3, 4, … 8). (C) Input conditions responsible for phase transitions between (C.1) non-deterministic to deterministic non-spiking and (C.2) non-deterministic to deterministic spiking phase transition. Input conditions include 1) inter-stimulus interval of the stimulus responsible for the transition (blue) compared to the unconditioned inter-stimulus intervals (orange), 2) histogram showing the relative presence of the specific transition category in relation to the number of input events, and 3) the ratios of stimuli types (excitatory: red and inhibitory: blue) of stimulus just before the transition (pre), of the stimulus responsible for the transition (post), and the expected, unconditioned stimuli type ratios (exp).
