In the software, the file Test.m fits to cortical S1 multiunit activity (MUA) the FHN dynamical model with Locus Coeruleous (LC) neuromodulatory inputs to a 1.5 sec stretch of spontaneous MUA activity.
The function test.m calls the following functions contained in the package:
-       FHN_Auto.m: Function which gets the model parameters and modulatory inputs and integrates the dynamics prediction using the auto-dynamical equations defined in [1].
-       FHN_Self.m: Similar to FHN_Auto but this functions computes the self-dynamical equations defined in SAfaai et al (PNAS 2015).
-       FHN_ep_Auto.m: Computes the cost functions of the model fit error and the MUA for auto-dynamical model.
-       FHN_ep_Auto.m: Similar to FHN_ep_Auto.m but for self-dynamical model.
-       FHN_OPT.m: Optimizes the fit error and estimates the self and auto dynamical model parameters. 
-      test.m: The function calls an example dataset DATA.m that contains Matlab data with the following structure used to run a test example of the codes:

    DATA.MUA: MUA activity
    DATA.Time: Time stams
    DATA.Input1: Input 1 to the dynamical model
    DATA.Input2: Input 2 to the dynamical model
    DATA.PARAMS: Estimated model parameters of the example trial.
