Figure 7.

Correlated activity in neighboring ganglion cells. Instantaneous spike rates and cross-correlations for three morphologically identified cell pairs are shown (A-C). A, An α (red)-β (blue) pair, which had a peak correlation of r = 0.70. B, A β(red)-γ (blue) cell pair with a peak correlation value of r = 0.71. C, Twoγ-cells. These cells had a peak correlation of r = 0.75. D, The peak correlations of all 10 pairs of morphologically identified cells. E, The average peak correlations for all cells in the young (P3-P9) group are compared with those in the older group (P15-P24). The two groups are not statistically different (t = -1.46; p = 0.156).
