Histogram of gold particles/random points ratio; gold particles were grouped in bins depending the distance (10, 20, 30, 40 nm) from each kind of membrane, at hippocampal glutamatergic synapses and surrounding glia

Journal Compilation Federation of European Neuroscience Societies and Blackwell Publishing Ltd</p> The percentage of the total number of gold particles that occurred in each bin was divided by the percentage of the total random points (within 40-nm distance) that occurred in the same bin; the ratio gives the distribution of receptors relative to a random distribution. A ratio > 1 for the shorter distance bins (10 nm and 20 nm), indicates a close association with the membrane observed. Note the higher ratios (arrows) for short distances at presynaptic active zone membranes, postsynaptic membranes overlying the PSD and astroglial membranes, for both AR (A) and P2YR (B
