Bayesian approach for tuning function determination demonstrated for simulated two-dimensional data. The synthetic dataset is 10K samples long and includes 264 spikes. (A) illustrates the probability mass function p_V(v) of the occurrence of combinations of mutual independent variables v₁ and v₂. The joint probability mass function p_V,S (v,s) of coincident variable and spike occurrence is shown in (B). Dividing p_V,S (v,s) by p_V(v) yields the conditional probability p_S|V (s|v) of observing a spike given any combination of the variables (C).
