Chemical synapses in the CA1 region of rat hippocampus in three groups (20000×). Black arrows indicate chemical synapses, and white arrows indicate changes described. A, B and C were respectively TLV group, OLV group and DEX group. The complete synaptic structure can be seen in A, and the presynaptic membrane contains A large number of synaptic vesicles. In B, some synapses were broken, with few synaptic vesicles and fuzzy synaptic connections. The complete synaptic structure was observed in C, and the presynaptic membrane contained synaptic vesicles
