Brain Scans Show Girls And Boys Equal At Math

By Katie Hunt, CNN (CNN) — Several studies have already debunked the myth that boys are innately better at math than girls, but those are largely based on analysis of test scores. Now, researchers also have brain imaging that proves young children use the same mechanisms and networks in the brain to solve math problems no matter their gender. The study was published Friday in the journal Science of Learning. “We’d studied the behavior of young girls and boys on mathematics tests, and we’d observed that their performance was statistically equivalent; they were indistinguishable. They’d developed the same abilities at the same rates in early childhood,” says Jessica Cantlon, a professor of developmental neuroscience at Carnegie Mellon University and the study’s senior author. “But there was this lingering question of what’s going on under the hood? Is it the same neural mechanism that allows them to accomplish this equivalent behavior?” To answer this question, Cantlon and her team got 104 kids between the ages of 3 and 10 to perform cognitive tests and watch videos of engaging math lessons while in an MRI scanner. It’s the first study to use neuroimaging to evaluate biological gender differences in the math aptitude of young children. “We looked at which areas of the brain respond more strongly to mathematics content in the videos and tasks, compared to non-math content like reading or the a...

Authors: Yu L, Yang Y, Wang C Abstract This chapter intends to review the progress in obtaining site-specific structural information for peptide assemblies using scanning tunneling microscopy. The effects on assembly propensity due to mutations and modifications in peptide sequences, small organic molecules and conformational transitions of peptides are identified. The obtained structural insights into the sequence-dependent assembly propensity could inspire rational design of peptide architectures at the molecular level. PMID: 31713196 [PubMed - in process]

ConclusionsSimilar to AD, the interpretation of [18F]THK5351 uptake in PSP is likely confounded by off-target binding to MAO-B binding sites. [18F]THK5351 is not sufficient in quantifying tau aggregates in PSP using the proposed rasagiline dosing regimen.

As radiographic predictive factors, some reports have focused on the region of ill-aerated lung, but none have focused on well-aerated lung. Our objective was to evaluate the relationship between computed tomography (CT) volume of the w...

AbstractThe aim of the study was to compare CE-MRV with DANTE-SPACE on a 1.5T MRI system for the diagnosis of DVT. The patients were diagnosed with deep venous thrombosis of the lower extremities based on swelling, pain, and superficial varicose veins of the lower extremities. MRI examination confirmed the diagnosis. DANTE-SPACE images were obtained before the conventional contrast-enhanced MRV, which uses gadolinium. The scanning field started from the end of the inferior vena cava to the end of the ankle, divided into five observation segments, namely, the common iliac vein, external iliac vein, femoral vein, popliteal v...

Abstract The application of image processing techniques for the analysis of CT scan images corresponding to lung cancer cells is gaining momentum in recent years. Therefore, it is of interest to discuss the use of a Computer-Aided Diagnosis (CAD) system using Computed Tomography (CT) images to help in the early diagnosis of lung cancer (to distinguish between benign and malignant tumors). We discuss and explore the design and significance of a CAD-CT image processed model in cancer diagnosis. PMID: 31719770 [PubMed]

Conclusions: The present study seeks to provide new insight in the pathophysiological mechanisms linking reduced kidney function to cardiovascular disease. In addition, we aim to enlighten predictors of adverse cardiovascular outcome in living kidney donors. The study is registered at Clinical-Trials.gov (identifier: NCT03729557).

Conclusions: Data produced in this study do not encourage ganciclovir treatment for UC patients. However, studies included in this analysis were observational, and thus, inherited severe selection bias. We suggest randomized controlled studies be conducted to make firm recommendations in this context. PMID: 31718340 [PubMed - as supplied by publisher]

In 1983, a health professional in her 30s walked into my office and said, “I’ve been healthy all of my life. A year ago, I came down with some kind of virus — sore throat, aching muscles, swollen lymph glands, fever. My fatigue was so bad I was in bed for nearly a week. Many of the symptoms gradually improved, but the terrible fatigue and difficulty thinking have not gotten better. They’re so bad I can’t fulfill my responsibilities at home or at work. This illness is affecting my brain, stealing my energy, and affecting my immune system. It’s keeping me from realizing my dreams.” T...
