Figure 11From: Sonic hedgehog (Shh)/Gli modulates the spatial organization of neuroepithelial cell proliferation in the developing chick optic tectumFano Factor (FF) analyses of binary signals. Log-log plot of the FF algorithm applied to binary signals obtained from control (A), GliA electroporated (B) and Shh non-ventralized (C) and tectal region of Shh partially ventralized electroporated dorsal midbrains (D). Means values of α (mean ± SD) are indicated in each case. α = the slope of the line estimated by least squares linear regression.Back to article page
