Figure 4From: Expression of AMPA receptor subunits at synapses in laminae I–III of the rodent spinal dorsal hornImmunostaining for GluR1 and GluR4 in lamina I. Confocal images that show immunoreactivity for GluR1 and GluR4, together with a merged image (right). Note that in this field the two types of immunoreactivity are contained in different puncta, with no co-localisation. This is a projection of 16 optical sections at 0.3 μm z-spacing. Scale bar = 5 μm.Back to article page
