Simulating neuroimaging data

It is possible to extract data from the LSNM simulations and transform it into simulated neuroimaging data. For that purpose, LSNM keeps track of the synaptic activity of each unit of a given model. Keeping track of synaptic activity at each unit means keeping track of the sum of all inputs to both inhibitory and excitatory elements of each individual unit at each simulated time step. LSNM writes out an output file called spec_pet.m, in matlab format, containing that data for each unit of the given model. You can use the data in that file to compute PET, fMRI, and MEG. There are a number of matlab scripts for those purposes, and they are contained in the directory $LSNM/code/postprocessing.
