This question might be better suited to a Statistics Forum, but I would need to know the MATLAB functions nevertheless.

Suppose I have a spike trains, each containing a burst in response to a similar input. Does it make sense to calculate the average autocorrelation for all these bursts? If so, what averaging method would be best , and how would I achieve this in MATLAB? I am slightly sceptical of simply taking

mean()

of all the autocorrelations - I lack the statistical temerity.

Thanks,

Linford

Re-reading my question, I fear it may not be completely clear: I have, say, 100 vectors. Each contains a burst of spikes, in response to a similar input. Can I compute the autocorrelation for each of these bursts and then somehow average them?

The reason I want to do this is because I have a series of such bursts for a control and "drug" situation, and I want to see how the drug affects the burst.

Thanks,
