A–F Prediction of LFP (A–C) and firing rate (D–F) using an odor transduction model (Eqs. (4) and (5)) combined with the linear-nonlinear model (Eqs. (1) and (2)). The transduction model was fitted to the average LFP (first 400 ms of the 20 ms and 200 ms stimuli), and the LN model was fitted to transform the average LFP to the average firing rate (2 s stimulus) (indicated by the dashed lines). Note that the model neglects receptor adaptation and the sustained activity. G, H Using the model to predict firing rate as a response to a complex stimulus. G Pheromone stimulus followed a frozen white noise pattern with a correlation time of 50 ms. H The model predicts the observed firing rate well. The predicted firing rate was multiplied by a factor of 0.77 to account for the lower concentration used in this experiment.
