Model inversion using spectra from rat auditory cortex. A: Upper panel: real data (dashed line) and model predictions (full line) showing a 1/ω spectral profile that is typically seen under anesthesia. The lower panel shows the conditional estimates (90% confidence intervals) of the neural field model parameters using empirical data from a single trial recording of auditory responses in the rat. The estimates lie close to the prior values (a log-scaling of zero), which were motivated by animal physiological studies (Jansen and Rit, 1995). B: Neural mass model estimates of the same data exhibit a similar fit (upper panel) and conditional estimates (lower panel).
