These are not single neuron spikes they are field potentials. I'm
using an in vitro model of epileptic activity by perfusing magnesium
free artificial CSF. What I would like to establish is whether there
is any degree of regularity to these trains of depolarizations
(~6-10/min) and see if this is altered when I co-perfuse drugs across
Autocorrelograms can reveal simple regularities in spike trains, e.g.
if many spikes are followed by another one at 30s then you'll get a
bump in the autocorrelogram. But since I've not found anything like
that what I need is a measure of higher-order patterns, though I'm not
sure even if I find one how to interpret that since it might be highly
