Fig. 3. — Comparison between the model and recorded PFC neuronal tuning curves. (a) Rastergrams for the P and the three (PV, CB, and CR) inhibitory neuron populations during the cue and delay periods. Instantaneous firing rates are color-coded. (b) Observed neuronal tuning curves (solid lines) during the delay period in the model simulations. Eight different cue positions are used. Dashed lines, spontaneous firing rate during the resting state. Parameter values that differ from the reference parameter set are , σ_E→PV = 162°, and . (c) Three kinds of recorded tuning curves in dorsolateral PFC during an oculomotor delayed response task, with the same conventions as in b. Solid line, the best Gaussian fit; dotted line, average firing rate during the last second of fixation. Note that the fast-spiking putative PV cell (Center) has a higher spontaneous firing rate and wider tuning than the regular-spiking putative P cell (Left), similar to what is found in the network simulations (b). An example of the inverted tuning curve is shown (Right). (Left and Center) Based on data from ref. 17.
