Synaptic vesicle area is increased in Gpt2-null CA1 stratum radiatum while number of synaptic vesicles per spine remains unchanged. A Representative images of spines in wild-type (top) and Gpt2-null (bottom) CA1 stratum radiatum at P18. Scale bar: 0.1 µm. B Quantification of the area of synaptic vesicles. Each dot represents the averaged area of synaptic vesicles in spines obtained from one animal. A minimum of 25 micrographs were used for each animal. **P = 0.001. C. Quantification of the number of synaptic vesicles per spine. Each dot represents the averaged number of synaptic vesicles obtained from one animal. A minimum of 25 micrographs were used for each animal. D Quantification of the post-synaptic density length. Each dot represents the averaged post-synaptic density length obtained from one animal. A minimum of 25 micrographs were used for each animal
