% Arguments:
|
|
% spikes: a cell array of vectors of spike times in seconds
|
|
% tmax: plot spike raster up to tmax seconds

% (x,y) pairs for start and stop of stroke
|
|
% plus nan separating strokes:
|
|
spiketimes = [spiketimes, ...
|
|
[times(:)'; times(:)'; times(:)'*nan]];
|
|
trials = [trials, ...
|

[ones(1, length(times)) * (k-0.4); ...

% convert matrices into simple vectors of (x,y) pairs:
|

% plotting this is lightning fast:

plot(spiketimes, trials, 'k')

ylabel('Trials');
