Abnormal Interhemispheric Functional Connectivity in Acute Pericoronitis: A Resting-State MRI Study.

Objective: Acute pericoronitis (AP) is a prevalent cause of odontogenic toothache which can significantly impact brain function. Previous research has predominantly concentrated on localized brain activity. However, the synergistic changes between brain hemispheres induced by toothache and resulting abnormal functional connectivity across the brain have not been comprehensively studied.

Acute Changes in the Resting Brain Networks in Concussion Patients: Small-World Topology Perspective.

Background: The acute changes that occur in the small-world topology of the brain in concussion patients remain unclear. Here, we investigated acute changes in the small-world organization of brain networks in concussion patients and their influence on persistent post-concussion symptoms.

Methods: Eighteen concussion patients and eighteen age-matched controls were enrolled in this study.
