Effects of EA on the non-motor behaviors of SD rats induced by 6-OHDA. A. In open
field test, anxiety-like was evaluated by measuring the total distance (mm),
distance in center (mm) and the time spent in center (%) of rats in the apparatus.
B. In Y maze test, the spontaneous alternation ratio was calculated in rats from NC
group, Sham group, 6-OHDA group or 6-OHDA+EA group. C. The immobility time (s) of
rats from each group was shown in forced swim test. D. The immobility time (s) and
the number of struggles of rats from each group were recorded in tail suspension
test. Data are expressed as mean ± SD. *P<0.05,
**P<0.01.
