Objectives

Narrative objectives1

To demonstrate using functional MRI that the duration of after sensation by thermal stimulation is associated with brain activity and functional connectivity.

Basic objectives2

Others

Basic objectives -Others

To evaluate the hypothesis that the duration of after sensation induced by repetitive thermal stimulation is associated with activity in specific brain regions and strength of brain function connectivity.

Other related information

From May 7, 2019 to December 31, 2023, the chronic pain patient group is selected from patients who satisfied selection criteria in the Department of Dentistry and Oral Surgery at Keio University Hospital or Kawasaki Municipal Ida Hospital for the treatment of chronic pain in the orofacial area.
The healthy group requests research cooperation through a staffing agency.
The subject answers the questionnaire and receives MRI under thermal stimulation on the upper arm.
