MATLAB:

Determine a list of all trials that have at least one ISI greater than 40 ms.

function ISI = compute_ISI(d)

n_trials = size(d,1);

ISI = [ ];

for k=1:n_trials

spike_times = find(d(k,:) == 1);

isi0 = diff(spike_times);

ISI = [ISI, isi0];

end

end

1) Display your results as a plot with trial number on the horizontal axis, and the vertical axis equal to:

0 if the trial does *not* have an ISI greater than 40 ms,

1 if the trial does have an ISI greater than 40 ms.

2) Label the axes appropriately, and include a title that is your name. (x axis time and y axis labled "Action Potential")
