Zones for measurement at the PSD. Synapse labeled with SynGAP (A) with superimposed mask (B) to illustrate zones for measuring amount of label in the PSD complex. The PSD core is defined as the area less than 40 nm from the postsynaptic membrane (between the postsynaptic membrane and upper dashed lines) and the adjacent area 40–120 nm from the postsynaptic membrane is defined as the contiguous network (between the upper and lower dashed lines). Each particle is assigned to the zone containing its center. Scale bar = 100nm.
