Figure 3: GluA1 receptors are present in post-synaptic sites within the ‘learning ganglia’.

Figure 3

Colocalization of GluA1 (green fluorescence) and PSD-95 (red fluorescence) in the buccal (top set of panels) and cerebral ganglia (bottom set of panels). The positions of neuronal cell bodies were mapped by using DAPI staining of the nuclei. The neuropile is indicated by an asterisk. The large panels on the right show the distribution of co-localized PSD-95 and GluA1 immunopositive pixels (real size of each pixel, 0.25 μm × 0.25 μm), in both the neuronal cell body region and the neuropile. Arrows indicate examples of neuronal cell bodies with particularly strong colocalization of GluA1 with PSD-95, both in the soma and the axon hillock. Scale bars represent 50 μm. This experiment was replicated three times.
