The Role of Inhibition in a Computational Model of an Auditory Cortical Neuron during the Encoding of Temporal Information

Temporal fidelity of synchronized and mixed neurons.
Only simulated neurons with an excitatory input strength between 3–6 nS were used in this analysis, such that synchronized and mixed neurons had a similar distribution of excitatory levels. a. Max vector strength distribution for acoustic pulse train responses in simulated neurons. Mean: sync = 0.93, mixed = 0.79, Wilcoxon rank sum test: P < 3.3 x 10-52. b. IPI synchronization limit distribution for acoustic pulse train responses in simulated neurons. Mean: sync = 10.2 ms, mixed = 7.7 ms, Wilcoxon rank sum test: P < 1.3 x 10-43. c. Max vector strength distribution for acoustic pulse train responses in real neurons. Mean: sync = 0.68, mixed = 0.60, Wilcoxon rank sum test: P = 0.16. d. IPI synchronization limit distribution for acoustic pulse train responses in real neurons. Mean: sync = 25.7 ms, mixed = 13.4 ms, Wilcoxon rank sum test: P < 0.02.
