“Rat Model of Mild Traumatic Brain Injury Shows Sensitization of Trigeminal Neurons and Increased Meningeal Blood Flow”

https://pubmed.ncbi.nlm.nih.gov/38115600

This study found that a closed head model of mild traumatic brain injury in rats results in sensitization of trigeminal brainstem neurons and increased meningeal arterial blood flow, suggesting that these neurons play a role in the neurovascular and sensory aspects of mTBI.
