Neuroanesthesia Research Laboratory

The Neuroanesthesia Research Laboratory directed by Oluwaseun Johnson-Akeju, MD, MMSc, at Massachusetts General Hospital conducts research that intersects medicine, neuroscience, mathematical modeling and engineering.


The goal of the Neuroanesthesia Research Laboratory, directed by Oluwaseun Akeju, MD, MMSc, at Massachusetts General Hospital, is to develop tools and strategies to optimize post-operative cognitive recovery.

The ability to perform surgery or invasive procedures safely and humanely relies on the delivery of general anesthesia—a practice that was first publicly demonstrated at Massachusetts General Hospital in 1846. General anesthesia is a reversible drug-induced state that consists of unconsciousness, amnesia, analgesia and immobility with maintenance of physiological stability. According to the New England Journal of Medicine, it is estimated that more than 60,000 patients in the United States receive general anesthesia every year for surgery. The brain, especially for older patients, often does not return to normal after general anesthesia. Some patients develop a serious deficit that comes and goes while others demonstrate a significant and persistent decline in performance on neuropsychological tests.

Our Research

Three major approaches of our research:

  1. Systems biology strategies to aid risk stratification of post-operative neurocognitive dysfunction
  2. Principled brain monitoring strategies to aid personalized anesthetic care
  3. Pharmaco-EEG strategies to aid drug discovery efforts

Interested in participating?

We are currently recruiting patients for the following studies:

  • Minimizing Neurological Dysfunction with Dexmedetomidine-induced Sleep (MINDDS) -  currently limited to patients over 65-years-old who are scheduled to have heart surgery at Mass General
  • Repurposing dexmedetomidine into an oral sleep therapeutic - currently limited to healthy volunteers 18-50 years of age
  • Additional studies of human neurophysiology and behavior during induction, maintenance and emergence from general anesthesia - typically limited to healthy volunteers 18-36 years of age

If you are interested in participating in any of the above studies, call us at 617-726-5186 or e-mail
