MIT Neurotech: A Journey Through the Brain


Editor’s note: This is the first installment in a series about emerging neurotechnologies. Join a pilot class of 12 PhD students at MIT as we explore how neuroscience is revolutionizing our understanding of the brain. Each post coincides with a lecture and lab tour at MIT created by the Center for Neurobiological Engineering. This experiment [...]

Enormous, Endangered, Epileptic Loggerhead Turtle Gets MRI Brain Scan

loggerhead turtle

How do you find out why a 1.5-meter-long endangered sea turtle is having epileptic fits? The first step is to find an MRI machine big enough to accommodate her not-so-ladylike girth. On June 25, “Snorkel,” a 68-kilogram loggerhead sea turtle (Caretta caretta), traveled more than 500 kilometers from her home at National Marine Aquarium (NMA) [...]

New wave of MRI-safe pacemakers set to ship to hospitals

This week Medtronic will begin shipping to hospitals in the United States the first pacemaker approved by the FDA as safe for most MRI scans. For consumers, it is a significant step in what is expected to be a wave of new MRI-compatible implanted cardiac devices. But this is an example of one technology chasing [...]

This blog is the fifth in a series of guest posts on technology and the brain to celebrate Scientific American Mind’s 10-year anniversary. The magazine’s special November/December issue similarly highlights the interface between code and thought in profiling a future, more digital YOU. Imagine having to spot a single grain of cereal at the bottom [...]

How Computational Models Are Improving Medicine [Video]

computational medicine

The more we learn about cancer, heart disease and Alzheimer’s, the more vexingly complex they seem—and the more elusive their cures. Even with cutting-edge imaging technology, biomarker tests and genetic data, we are still far from understanding the multifaceted causes and varied developmental stages of these illnesses. With the advent of powerful computing, better modeling [...]

Nodding Disease Origins Remain Unexplained

uganda nodding disease

A strange illness has been killing thousands of young people each year, and recently it has started claiming even more victims in Africa. Called nodding disease, it usually strikes children at the age of 4 or 5 years and starts with occasional bouts of uncontrolled nodding. As the disease progresses through adolescence, the nodding often [...]

Patients Get More Unnecessary Scans from Doctors Who Own Equipment

doctor and patient MRI scan

More and more physicians are investing in their own imaging equipment. But when a doctor stands to make money on each MRI he or she orders, it doesn’t take a brain surgeon to figure out that they might be inclined to order too many scans. Patients with back problems whose orthopedic surgeons referred them for [...]

Will CT Scans and MRIs Kill the Autopsy?

body with toe tag

Instead of cutting into a dead body to determine the cause of death, some coroners are already calling in a radiologist. But can CT (computed tomography) and MRI (magnetic-resonance imaging) tests accurately assess the recently deceased? Formal autopsies have been on the decline for decades, due in part to tightening budgets. In the U.S. less [...]

Do You Use GPS? Say “Thanks” to Norman Ramsey (1915–2011)

Norman Ramsey from Nobel Prize

Norman F. Ramsey may not be a household name, but he was a giant of 20th-century experimental physics. His basic-science work earned him the 1989 Nobel Prize in Physics and laid the foundation for technologies now used by millions of people. He died last Friday at the age of 96. In exploring how atoms and [...]
