Figure 1. Syn1-cre expression is variable across different brain regions.

The Cre-mediated activation of MeCP2 ^mCherry fluorescence was visualised in brain sections from Syn1-cre,Mecp2 ^{mCherryStop/y} mice, and Mecp2 ^{mCherryStop/y} and Mecp2 ^mCherry/y control mice. Images shown are taken from one mouse per genotype. All mice used were male Mecp2 hemizygotes. Sections were stained for DAPI and immunolabelled for the neuronal marker NeuN. Scale bars: 50 µm.
