Neurons integrate inputs from thousands of afferents.Similarly, some experimental techniques record the Extra Handsets pooled activity of large populations of cells.When cells in these populations are correlated, the correlation coefficient between the collective activity of two subpopulations is typically much larger than the correlation coefficient between individual cells: Storage Leg Desk The act of pooling individual cell signals amplifies correlations.

We give an overview of this phenomenon and present several implications.In particular, we show that pooling leads to synchronization in feedforward networks and that it can amplify and otherwise distort correlations between recorded signals.
