Generate a Poisson spike train in MATLAB: 1.Select a small At (0.001 seconds) 2.Select a firing rate (in Hz) 3.Make a time vector (100 seconds, step size is At) 4.Spikes=rand(size(time_vector)) < rate * At; 5.Plot your spike train 6.Plot the ISI histogram for your spike train and overlay the Poisson ISI distribution (theoretical) hint: make tau step sizes and bin sizes for your histogram the same 7.Calculate the CV for your ISI 8.Submit code and word/pdf document with 2 plots and CV
