correlated activity at this point takes place mostly outside of minicolumns with the same index (almost no gray areas)
cluster of 8 cells out of which a max 2 might be with the same index; cells of between 4 and 8 same index minicolumns are correlated; although fluctuating stronger than the triangle above, this structure has some stability over time
a lot of space between the triangle and the other structures: the rest of the network does not seem on the same page...
