Figure 4From: Steerable-filter based quantification of axonal populations at the developing optic chiasm reveal significant defects in Slit2−/− as well as Slit1−/−Slit2−/−embryosExpression of Slit1 and Slit2 around the E13.5 optic chiasm. In situ hybridizations on horizontal sections through the ventral diencephalon: areas of expression appear pale yellow. Expression of Slit1 is strong around the point of entry of the optic nerve (o.n.); expression of Slit2 is strong anterior to this point. Olfactory epithelium = o.e. Scale bar = 200 μm.Back to article page
