Hello -

I'm plotting data from microelectrode recordings into anatomical space. Because patients can have variable recording sites, the spatial density of all plotted statistical is unequal. How can I test whether my plotted statistical values are observed above chance, while accounting for the variable number of recordings/samples at each voxel?

If it clarifies things, I have the data plotted both individually (1 statistical value - 1 recording site coordinate), and as combined datasets (1 containing the number of recordings at each voxel, 1 containing the summed statistical values at each voxel).

Thank you (and sorry if this is obvious),
Pete
