Stroke Stopper
A new "wingspan" stent helps
restore blood flow for
patients with intracranial
atherosclerotic disease, or
ICAD. Surgeons insert the
stent up the leg arteries,
guide it to the brain, then
let its wire mesh expand,

GPS For The Brain
Neurosurgeons' jobs are made
easier by a 3-D CT scan
produced by an advanced
imaging system. It produces
a computerized image of
blood vessels and
surrounding soft tissue,
which can be rotated for

Inside the Brain
Children who have
speech-impairing strokes
often learn to talk again,
while adult stroke victims
can lose their verbal
abilities for good. By
giving reading and verbal
tests inside the MRI,

Brain Scans Of The Future
Psychologists have found
that thought patterns used
to recall the past and
imagine the future are
strikingly similar. Using
functional magnetic
resonance imaging to show

Neurologists Use New Brain Scanning Device To Better Control Seizures
Doctors are now using a new kind of brain scan called magnetoencephalography (MEG), which measures brain activity in real time. In some cases, MEG can pinpoint the source of an epileptic seizure much ... > more -
Neurologists, Imaging Scientists Use Medical Physics to Spot Disease in Blood Vessels
A new brain-imaging method allows physicians to diagnose Alzheimer's before its onset. A radioactive dye is injected in the blood and travels to the brain, where it attaches to plaque deposits of ... > more -
Neurosurgeons Can Now Remove Brain Cancer Endoscopically
For more than a century, neurosurgeons have accessed the brain through the nose, but only recently did they successfully removed tumors with such minimally invasive procedures, leading to patients' ... > more -
Neurosurgeonýs Drive Propels Him From Border Fence To Faculty
Physician scientist Alfredo Quinones has come a long way since illegally entering the United States. Today he is a faculty member at Johns Hopkins University. Quinones is a respected brain surgeon ... > more -
Cognitive Psychologists Show Conversations Lower Visual Abilities
A study showed that the part of the brain that controls vision becomes less active when people focus on something visually while having a conversation -- underscoring the hazards of talking on your ... > more -
Neurosurgeons Cut Surgical Procedure Time with New Device
In a method called deep brain stimulation, certain movement disorders are treated by implanting wires in the brain that deliver electrical signals. The surgical procedure can last up to eight hours, ... > more -
Cardiologists Employ Biomedical Engineering to Safeguard Heart Patients
To prevent strokes in at-risk patients who suffer from atrial fibrillation, an abnormal heart rhythm, researchers have devised a mechanical alternative to common drug treatments. In the procedure, ... > more -
Molecular Biologists Devise Strategy To Starve Brain Tumors
Brain tumor researchers have found that brain tumors arise from cancer stem cells living within tiny protective areas formed by blood vessels in the brain. Killing those cells is a promising ... > more -
Acoustic Study Shows Safe Listening Levels
Loud, sustained sound can damage tiny hairs in the cochlea, and yet 80 percent of people listen to personal music devices at dangerous levels above background noise, a study by acousticians shows. ... > more -
Vision Researchers Test Theory on Visual Orientation
Vision researchers suspect that people who do not need maps to find their way may be remembering visual landmarks. To test this theory, the scientists are having volunteers navigate through a virtual ... > more
