| Research Abstract |
There are subcortical and cortical centers above the brainstem that induce swallowing movement, however, their specific role and connections are not well understood. We applied functional near infrared spectroscopy (fNIRS) for brain mapping in swallowing and swallow related movements. Twenty five of volunteers and seven patients with dysphagia were examined by fNIRS. Subjects sitting on the chair were put 34 channel holder of OMM 2000 (Shimadzu, Kyoto, Japan). BA 4, BA 3,1,2, BA 6 were activated both in command and noncommand swallow in our study. The haemodynamic pattern during swallowing appeared different in command versus noncommand tasks in BA 6 and BA 40. Our findings suggest that the sensory input is more important in noncommand than in command swallow. These data show that cortical process to initiate swallowing movements is altered by the triggers.
