Investigating Traumatic Brain Injury
Our mission at the Laboratory for NeuroImaging of Coma and Consciousness (NICC) at Massachusetts General Hospital is to determine how patients recover consciousness after a severe traumatic brain injury and to promote the recovery process.
We use advanced structural and functional imaging techniques to identify brain networks whose connectivity and activation is critical to the restoration of consciousness.
We believe the identification of these brain networks will allow clinicians to provide patient families with more accurate prognoses and will ultimately enable the development of personalized treatments aimed at promoting recovery.
While the NICC’s mission is to improve outcomes for civilians and military personnel with traumatic brain injury, we also partner with other labs to study recovery of consciousness in patients with coma caused by cardiac arrest, hemorrhage and stroke.
Ongoing Research StudiesTraumatic Coma RESPONSE Study
Traumatic Coma RESPONSE Study (REsting and Stimulus-based Paradigms to detect Organized NetworkS and predict Emergence of consciousness): an MRI and EEG study of brain network structure and function in patients with acute traumatic coma.
The primary goal of this multimodal neuroimaging study is to determine if acute, advanced MRI and EEG predict 6-month outcomes better than current clinical predictors.
The secondary goal of this study is to identify longitudinal changes within brain networks that enable recovery of consciousness and communication.
Ex Vivo Connectomics of Traumatic Coma
Ex Vivo Connectomics of Traumatic Coma: a postmortem imaging and histopathological study of brain specimens from patients who have died after severe traumatic brain injury.
The primary goal of this correlative histo-radiologic study is to identify the specific circuits within the brainstem ascending arousal network and cortical default mode network that are necessary and sufficient for recovery of consciousness after traumatic coma.
Secondary goals of this study include:
