High-level description . Are neural populations in the visual cortex homogeneous ensembles or are they to some degree structured? If neural populations are structured, how is their organisation related to pair-wise interactions between neurons? In this study, we analyse recordings from neural populations in V1 and V4 visual areas of macaque monkeys and find out that responses of these neural populations are structured, and that this structure carries information about the correct choice of the animal. We also find that in visual area V4, but not in V1, neurons with similar response patterns tend to be more strongly correlated and synchronised compared to neurons with opposite selectivity. This suggests that neurons with the same selectivity form functional subnetworks.
