Figure 1. Spatial restraint stress caused depressive phenotype with significant decrease in neurotransmitters.
(A) Immobility time of depressive mice was significantly elevated compared with control group in FST. (B) Immobility time of TST in stress mice and control group. Note that a depressive-like phenotype has been developed after spatial restraint stress. Levels of 5-HT (C) and dopamine (D) in hippocampus were subsequently examined by HPLC, showing the resultant declines of these depression-associated neurotransmitters. *P<0.05, **P<0.01 versus control group. N = 9–10.
