I witnessed a breakup yesterday in the middle of MIT’s vast Infinite Corridor—a hallway known for its heavy traffic and long stretch of straightness. Finals are upon the undergraduates, so perhaps tensions were a bit high for the young, failing couple. Something, however, had clearly pushed the girl overboard. Her boyfriend had fallen dramatically to [...]

Neuroscience can be lots of fun, but perhaps even more so when researchers study the brain’s Laughter Perception Network. In a new study researchers found that the brain responds differently to fMRI imaging of ticklish versus socially complex laughter.

At right is a picture of someone’s brain as seen through functional magnetic resonance imaging or fMRI. This particular subject is taxing his neurons with a working memory task—those sunny orange specks represent brain activity related to the task. fMRI images show the brain according to changes in blood oxygen level, a proxy for degree [...]

Medical school might be a long, slow slog, but once doctors have their training, they can often make diagnoses in a matter of moments. New research suggests that doctors actually identify an abnormality in less than two seconds—not much longer than it takes them to name an animal or a letter of the alphabet. Twenty-five [...]

By simply gazing at a picture of their beloved, undergraduates in a recent study were able to substantially reduce their experience of pain. The effect occurs thanks to a boost in the [...]

Among the more than a quarter of a million published functional magnetic resonance imaging (fMRI) studies are assays that have purported to locate our mental experiences of religion, love and even the future in the brain. Recently, researchers even investigated the reliability of the scans to find out whether they should hold up in court [...]

In a room tucked next to the reception desk in a colorful lobby of a Park Avenue office tower, kids slide into the core of a white cylinder and practice something kids typically find quite difficult: staying still. Inside the tunnel, a child lies on her back and looks up at a television screen, watching [...]
