Power spectral density (PSD) and estimation of the scaling index β. Log-log plots of the PSD of mNEc density signals obtained from controls (A) and GliA electroporated (B) and Shh non-ventralized (C) and tectal region of the partially ventralized Shh electroporated dorsal midbrains (D). Means values of β (mean ± SD) are indicated. The slopes of the lines (red lines) fitted by least squares linear regression is – β.
