a Representative 3D dSTORM reconstruction of LRRTM2 (cyan) and Homer1 (red). b LRRTM2 Homer1 synaptic abundance n = 232 synapses from 3 independent experiments (left) and number of SSDs n = 151 synapses from 3 independent experiments (right). LRRTM2 localization distance (c) and SSD distance (d) to Homer1 centroid. The mean and 95% confidence interval of Poisson fitted distribution are indicated on the graph. e Representative 3D dSTORM reconstruction of LRRTM2 (cyan) and Nrxn1 (left) or Nrxn3 (right; red) at Homer1+ synapse (green) in an enface view. f Nrxn1 is farther from LRRTM2 SSDs than Nrxn3, p = 0.0135; Mann–Whitney test (two-tailed). g Representative 3D dSTORM reconstruction of GluD1 (cyan) and Homer1 (red) in an enface view. h GluD1 Homer1 synaptic abundance n = 196 synapses from 3 independent experiments (left) and number of SSDs n = 134 synapses from 3 independent experiments (right). ij GluD1 localization distance (g) and GluD1 SSD distance (h) from the Homer1 centroid. The mean and 95% confidence interval of the Poisson fitted distribution indicated on the graph. k Representative 3D dSTORM reconstruction of GluD1 (cyan) and Nrxn1 (left) or Nrxn3 (right; red) at Homer1+ synapse (green) in an enface view. l Nrxn1 is closer to GluD1 SSDs than Nrxn1, p = 0.0314; Mann–Whitney test (two-tailed). Number of synapses and independent experiments are indicated in the figure. Bar graphs and line graphs: average ± SEM. Violin plots: median ± upper and lower quartiles. *p < 0.05.
