Figure 4.
The number of synapses including subtypes of synapse in CA1 (*P <.05; **P <.01; ***P<.001) (∆: vehicle group; ▲: vortioxetine; ▽: fluoxetine). (A) The total number of synapses was significantly higher in the vortioxetine group compared with the vehicle and fluoxetine groups. (B) The number of nonperforated spine synapses was significantly higher in vortioxetine group compared with the vehicle and fluoxetine groups. (C) The number of perforated spine synapses was significantly higher in the vortioxetine group compared with the vehicle and fluoxetine groups. (D) The number of shaft synapses was not any different in the vortioxetine group compared with the vehicle and fluoxetine groups.
