Advanced Visualization

 

When you close your eyes and visualize an important moment from the past, your brain may use the same eye movement patterns to reconstruct images long after you’ve originally seen them. It may seem like science fiction, but a study published in Cerebral Cortex found evidence of the phenomena.

Why does it seem like when alcohol gets involved, people often exhibit more aggressive behavior thanks to “liquid courage”? According to a group of international researchers, it’s because changes occur in the prefrontal cortex—the area of the brain charged with tempering a person’s aggression—after two drinks.

 

According to a recent study published in JAMA Neurology, memory decline and the potential to develop Alzheimer's disease may increasingly accelerate with age in certain individuals. 

A group of international researchers has discovered two large proteins in the brain that work together in producing its ‘stop’ and ‘go’ functions, much like a children’s game of “Red Light, Green Light.”

We put on our headphones every day, but who considers what allows singers to reach the high notes? Swiss researchers, that’s who.

 

Recent Headlines

Researchers develop graphene-based detection of brain cancer

Graphene’s resume is impressive: It’s 200 times stronger than steel, conducts heat and electricity with the utmost efficiency, and is the thinnest material known to man. The two-dimensional compound is made of a hexagonal lattice of carbon atoms, with applications ranging from solar power to tennis rackets.

Diluted gadolinium works well at minimizing ghosting artifacts on liver MRI

Comparing two methods of administering gadolinium-based contrast for MRI exams head to head, researchers have found that dilution with saline is better than a reduced injection rate at minimizing arterial-phase artifacts. 

Contrast-enhanced sonography a ‘sound’ alternative in pediatric advanced imaging

Off-label use of contrast-enhanced ultrasound (CEUS) may be the best advanced-imaging choice—safe, accurate and cost-effective as compared to guideline-recommended CT and MRI—for examining children in many instances, according to a British study published online Dec. 13 in the American Journal of Roentgenology. 

New technology creates 2D and 3D images of children with musculoskeletal conditions

A new imaging system has been installed at the Orthopaedic Institute for Children (OIC), now providing the most precise and safest way to diagnose musculoskeletal conditions in children. 

RSNA 2016: Keynote encourages radiologists to embrace evolving technology to treat cancer

On the third day of RSNA, attendees packed the main auditorium to see a keynote address on advancing imaging technologies and techniques that will become useful in efforts to treat cancer. 

Novel PET compound upends the field at detecting Alzheimer’s-associated amyloid

Washington University researchers say they have developed a novel PET tracer that is significantly better than FDA-approved compounds at detecting amyloid clusters in patients with suspected Alzheimer’s disease. 

Continuous imaging shows cells during limb regeneration

Regeneration of limbs may be restricted to lizards and crustaceans, but science is no less interested in studying just how cells accomplish the amazing feat. For the first time, researchers have been able to record just how epidermal cells act during regrowth after amputation.

Hospital's new intraoperative MRI provides real-time images

Nicklaus Children's Hospital, a part of Miami Children’s Health System, has recently installed a new intraoperative magnetic resonance imaging (iMRI) system that is able to differentiate between healthy and unhealthy brain tissue and improve accuracy for surgeons removing tumors.

MRI captures electric brain stimulation in action

Researchers have developed an MRI method to get a visual on electric currents affecting the human brain immediately after sessions of transcranial direct current stimulation (tDCS).

New tau PET tracer carries potential to advance Alzheimer's testing

There’s a new way to detect the buildup of tau proteins in living brains, according to research published in the journal Brain. The method uses PET imaging to see in which regions of the brain the protein is accumulating. It may also possibly reveal clues about the potential for Alzheimer’s or other tau-related cognitive diseases in individual patients—and pave the way for new types of Alzheimer’s drugs.
