Nature, meet nurture

(Harvard Medical School) Is it nature or nurture that ultimately shapes an organism? A new study reveals a dramatic landscape of gene expression changes across all cell types in the mouse visual cortex after a sensory experience, many linked to neural connectivity and the brain's ability to rewire itself to learn and adapt.

Acontroversial study recently published inJAMA Pediatrics has posed possible but largely unfounded links between autism and ultrasound technique and frequency. According to researchers from Boston University School of Medicine, there is a possible correlation between depth of ultrasound penetration during the first and second trimesters and autism. The researchers evaluated sonograms of 420 children, 107 with autism, 104 with developmental delay, and 209 with typical development. They looked at the frequency of ultrasound scans and penetration depth amongst the three groups. They found that mothers of children with au...

A new study from the National Institutes of Health has found that acute stroke patients who undergo MRI are highly susceptible to gadolinium leakage into the eyes. In astudy published inNeurology, the group of researchers led by Emi Hitomi, a post-baccalaureate intramural research training award fellow, evaluated 167 patients who received MRI exams upon being admitted to the hospital. Two hours and/or 24 hours after the MRI, patients underwent a fluid-attenuated inversion recovery (FLAIR) imaging exam. Gadolinium leakage into ocular structures (GLOS) were identified in 76 percent of patients. At the two-hour exam, GLOS occ...
