Illustration of fits of feedforward thalamocortical model (Eq. 8) to data from experiments 1–3. Each dot corresponds to the experimentally measured layer-4 firing rate at a specific time point plotted against the model value of . The red dots are corresponding experimental data points taken from the first 5 ms after stimulus onset (for all 27 stimuli). These data points show the activity prior to any stimulus-evoked thalamic or cortical firing and represent background activity. The solid green curve corresponds to the fitted model activation function .
