Research Snapshot: Unmatched insights into deep brain stimulation through MRI

Deep brain stimulation (DBS) is a procedure that is used to treat movement disorders including Parkinson’s disease, tremor and dystonia. To improve symptoms, a DBS lead (insulated wire) is surgically inserted deep within the brain in sites known to control movement.

Electrical impulses are sent from the neurostimulator, also known as a brain pacemaker, to the lead implanted in the brain. The stimulation changes the pattern of electrical activity in the brain into a more normal pattern, thereby improving symptoms and returning more normal movement to patients.

Choosing the target location for the lead is of critical importance. Standard protocol among physicians around the world is to use a brain atlas developed from two French women who donated their brains to science many years ago. From there physicians superimpose the patient’s own brain MRI images and calculate a plan to implant the electrodes in the brain.

Sen. Jeremy Miller impressed with U and MnDRIVE Neuromodulation research

In late June, the U of M hosted Minnesota Senator Jeremy Miller for an educational visit to learn more about the exciting neuromodulation research and technology taking place as part of the MnDRIVE brain conditions initiative.

During his visit Sen. Miller had the opportunity to tour the campus, meet and welcome new Minnesota men’s basketball coach Richard Pitino and hear from students and faculty about their research.

“I believe it’s extremely important for legislators, especially those on the higher education committee, to see and understand what our higher education institutions are doing,” Miller said.

U of M study reveals rats show regret, a cognitive behavior once thought to be uniquely human

New research from the Department of Neuroscience at the University of Minnesota reveals that rats show regret, a cognitive behavior once thought to be uniquely and fundamentally human.

Research findings were recently published in Nature Neuroscience.

U of M study: Reduction in neurosurgical resident hours appears to have no significant positive effect on patient outcomes

A reduction in neurosurgeon resident duty hours appears to result in no significant changes in patient outcomes, according to new research from the Department of Neurosurgery at the University of Minnesota. The reduction in resident duty hours was mandated in 2003 by the Accreditation Council for Graduate Medical Education (ACGME) when it imposed a mandatory maximum 80-hour work-week restriction on medical residents. Prior to this mandate, residents often worked in excess of 100 hours per week.

Findings were published today in the Journal of Neurosurgery.

U of M expert: U.S. still has work to do to reduce hospital readmissions post stroke

There have been numerous advances in acute stroke care and in preventive therapies after stroke. Yet despite these improvements, a recent University of Minnesota study found there is still room for improvement in reducing the rate of stroke patients re-admitted to the hospital.

In fact, the study discovered that one year after a stroke, an astounding 49 percent of patients end up back in the hospital with an acute illness. Worse, 24 percent of stroke patients pass away within a year of their stroke. The statistics paint a portrait of a nation that can, and should, do better.
