Artery-clearing surgery after stroke should be delayed

Treating stroke is a race against time. To prevent brain damage and save lives, physicians have to diagnose and treat strokes as quickly as possible. Now, a new study suggests doctors can reduce risks by delaying a commonly performed follow-up surgery that clears fatty deposits from an artery in the neck. Shown is senior author Greg Zipfel, MD.

Brain regions ‘tune’ activity to enable attention

The brain appears to synchronize the activity of different brain regions to make it possible for a person to pay attention or concentrate on a task, scientists at the School of Medicine have learned. Pictured is the study’s first author, graduate student researcher Amy Daitch.

Stroke prevention surgery less effective than meds, lifestyle change

The final results of a stroke-prevention study in patients with narrowed brain arteries confirm earlier findings: Medication plus lifestyle changes are safer and more effective for preventing stroke than a surgical technique called stenting. Pictured is a narrowed brain artery kept open with a stent.

Procedure to open blocked carotid arteries tested

Doctors at the School of Medicine are investigating a new minimally invasive procedure to open blocked carotid arteries in patients whose poor health or advanced age makes the traditional open surgery too risky. Pictured are carotid arteries, which feed blood to the brain.

Daydreaming simulated by computer model

Scientists have created a virtual model of the brain that daydreams like humans do. They hope the model will help them understand why certain portions of the brain work together when a person daydreams or is mentally idle. Shown is the study’s senior author, Maurizio Corbetta, MD.
