Correlation coefficient in the stim or bckg intervals for each of the 64 pictures between any two sites. The correlation coefficient was computed from the corresponding LFP variable. The correlation coefficient is color coded (see scale at the bottom, the diagonal is 1 by definition, the matrix is symmetrical). The dotted lines indicate separate penetrations.

Average statistics of the correlation coefficients computed between the responses from two sites. For each site, the response contains the corresponding LFP variable for each of the 78 different pictures.
stim = stimulus interval [100,300) ms with respect to stimulus onset
bckg = background interval [-200,0) ms with respect to stimulus onset
all = all possible pairs of sites
penetration = sites within the same penetration
