Recent work has shown that correlations also profoundly shape other important functions performed by neural populations, including generating codes across multiple timescales and facilitating information transmission to, and readout by, downstream brain areas to guide behaviour.
We show that correlations in the noise inputs of neurons not only decrease information transmission but also immediately reduce the optimal population noise ...
