Electroacupuncture Involved in Motor Cortex and Hypoglossal Neural Control to Improve Voluntary Swallowing of Poststroke Dysphagia Mice

Figure 2

The brain and lower jaw blood perfusion changes at before and after electroacupuncture in the PSD model.(a) Electroacupuncture parameters: continuous wave, 1 mA, 2 Hz, and 15 min. Acupoint: Lianquan (CV 23). (b) The brain and lower jaw of LSCI in each group: sham EA = lack of electric stimulation, after EA (acute) = EA stimulation once, and after EA (chronic) = EA stimulation for 3 days. (c) Motor cortex perfusion: , target 1 = noninfarction, target 2 = infarction, , normal vs. others group (target 1): . Target 2 vs. target 1: in others group except normal. Before EA vs. after EA (acute) (target 1): #; before EA vs. after EA (chronic) (target 1): ##. Before EA vs. after EA (acute) (target 2): , before EA vs. after EA (chronic) (target 2): . After EA (acute) vs. after EA (chronic) (target 2): ##. After EA (acute) vs. after EA (chronic) (target 2): △△. (d) Swallowing muscle perfusion: , , compared with normal, in others group. Before EA vs. after EA (acute): ##. Before EA vs. after EA (chronic): ###. After EA (acute) vs. after EA (chronic): △△.
