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.

Literature review suggests most fMRI findings have been unreliable at best

A new analysis of the literature on fMRI suggests that a shortcoming in the most popular software systems used to evaluate the imaging data—SPM, FSL and AFNI—may have caused all three to produce false positive findings at a 70 percent clip from 1992 to 2015. 

Gray matter differences imaged in diabetic teens

Prior research has established that teenagers with type 2 diabetes have different gray-matter volumes and poorer cognitive function than their nondiabetic peers. A new MRI-based study at Cincinnati Children's Hospital Medical Center has imaged the particular regions in which the differences occur. 

Diffusion MR proves adept at predicting concussion outcomes

Diffusion tensor MRI can be used to separate concussion patients who are likely to fully recover within a year from those who are likely to suffer longer-term effects, pointing to the most appropriate treatment pathways for each. 

Sheryl Crow named Hologic's national celebrity spokesperson for breast cancer educational campaign

Hologic, a developer, manufacturer and supplier of diagnostic products, medical imaging systems and surgical products, has announced a partnership with singer, songwriter and breast cancer survivor Sheryl Crow.

MRI may illuminate new avenues for schizophrenia treatment

Using MRI with covariance analysis, researchers have revealed tissue increases over time in the brains of patients with schizophrenia. The increases suggest these brains may be compensating for lost capacity and perhaps trying to protect themselves against further damage. 

FDA approves stand-alone 3D screening with Siemens Tomosynthesis Platform

Siemens Healthineers has received the approval of the FDA in the use of their Mammomat Inspiration with Tomosynthesis Option, the first and only digital mammography system to use a 3D digital breast tomosynthesis (DBT) platform as a stand-alone screening and diagnostic system.

Mother’s voice lights up child’s brain, and the connectivity predicts social skills

Children respond to their mothers’ voices differently than they respond to the voices of women they don’t know. That’s a no-brainer. But it’s something of a revelation to observe specific regions of a kid’s brain lighting up in fMRI when Mom speaks—and to find that the strength of connections between regions predicts how adept the child will become at social communication. 

fMRI shows prayer beating back alcohol cravings in the brain

After looking at drinking-related images and then reciting prayers as part of a recent study, 20 long-sober members of Alcoholics Anonymous reported less craving for a drink than when they read irrelevant news or remained passive. Meanwhile, fMRI confirmed the effect, revealing participants’ brains lighting up most during the prayer interim. 

Survey: Severe stroke prognoses differ depending on the doctor

A survey of 742 physicians across the US found that after a intracerebral hemorrhage (ICH), doctors make varied recommendations and very different decisions regarding care.

Siemens partners with Case Western on MR ‘fingerprinting’ project

Siemens healthcare has partnered with Case Western Reserve University to advance the development of magnetic resonance fingerprinting (MRF), an innovative imaging method capable of analyzing tissues to speed diagnosis of certain diseases.
