Optical imaging discovers secret of baby's first words
A new study could explain why "papa" and "mama" are often a baby's first words: The human brain may be hard-wired to recognize certain repetition patterns.
A new study could explain why "papa" and "mama" are often a baby's first words: The human brain may be hard-wired to recognize certain repetition patterns.
University of British Columbia postdoctoral fellow Judit Gervain and a team of researchers from Italy and Chile used optical brain imaging techniques to document brain activities of 22 newborns exposed to record-ings of made-up words. The researchers mixed words that end in repeating syllables-such as "mubaba" and "penana"-with words without repetition-such as "mubage" and "penaku." They found increased activity in the temporal and left frontal areas of the newborns' brains whenever the repetitious words were played. The study appeared in the Aug. 26 online issue of the Proceedings of the National Academy of Sciences.
Study Reaffirms Low Risk for csPCa with Biopsy Omission After Negative Prostate MRI
December 19th 2024In a new study involving nearly 600 biopsy-naïve men, researchers found that only 4 percent of those with negative prostate MRI had clinically significant prostate cancer after three years of active monitoring.
Study Examines Impact of Deep Learning on Fast MRI Protocols for Knee Pain
December 17th 2024Ten-minute and five-minute knee MRI exams with compressed sequences facilitated by deep learning offered nearly equivalent sensitivity and specificity as an 18-minute conventional MRI knee exam, according to research presented recently at the RSNA conference.
Can Radiomics Bolster Low-Dose CT Prognostic Assessment for High-Risk Lung Adenocarcinoma?
December 16th 2024A CT-based radiomic model offered over 10 percent higher specificity and positive predictive value for high-risk lung adenocarcinoma in comparison to a radiographic model, according to external validation testing in a recent study.
