Immunostaining for GluR2, GluR3 and GluR4 in lamina I. a: A confocal image from a parasagittal section, showing a cluster of GluR4-immunoreactive puncta that appear to outline a single dendrite in lamina I. The boxed area is shown in b-e. b-e: part of the field shown in a, scanned to reveal GluR4, GluR3 and GluR2, together with a merged image. The GluR4-positive puncta are also GluR2- and GluR3-immunoreactive, and 2 of these are indicated with arrows. This is a projection of 19 optical sections at 0.3 μm z-spacing. Scale bar = 10 μm.
