Morphology of the spinal cord in wild-type and GluR5^-/- mice. (A) Nissl-stained coronal sections through the spinal cord of a representative wild-type (left) and GluR5^-/- (right) mice. No obvious anatomical difference between these two strains was detected. Scale bar: 1 mm. (B) Nissl-stained sections depicting the substantia gelatinosa of wild-type (left) and knock-out (right) animals. No gross anatomical difference was detected when comparing both groups. Scale bar: 200 μm.
