Statistical analysis of large-scale retinal ganglion cell recordings

Michael Berry, William Bialek, and their research teams have found that retinal ganglion cells, the nerve cells along the back of our eyes that transmit visual signals to the brain, organize their actions based on communications they have with other individual cells rather than on group-style discussions. The findings, derived from experiments with and mathematical models of groups of 40 cells in the retinas of salamanders, could shed light on how brain cells work as a team.




Pairwise interactions can have global effects: at left, neurons A and B don't interact directly, but are highly correlated; at right, neurons A and B have a strong positive interaction, but this is frustrated by the negative interaction between pair A and C
