New paper out: removal of spurious correlations between spike and LFPs
A lot of papers have been looking at correlations between spikes and LFPs recently, to figure out how the two signals relate to each other (do LFPs drive spikes or vice versa? Is some of what we usually consider neural noise really coupling to the local network measured by the LFP?). One thing that has

Getting a plot with transparency to export in a vector format (e.g. eps) in Matlab
If you have a plot where one of the objects has the property facealpha or edgealpha set to something else than 1, Matlab will choke when attempting to export the figure to eps (it will render the plot as a low-res bitmap and stick it in an eps file if you use exportfig). The solution:
