Dialog / A surprising pathway that lets the striatum talk directly to the auditory cortex
For decades, neuroscientists have thought about communication between the cerebral cortex and the basal ganglia in a fairly linear way. The cortex sends information into the basal ganglia, where that information is processed ...
Medical Xpress / Lead-contaminated soil tracked indoors can create hazardous indoor conditions even in houses without lead paint
Lead contamination in soil tracked inside homes can cause dangerous indoor lead dust levels even in residences with no interior lead-based paint, according to researchers with the Rutgers Environmental, Occupational and Health ...
Medical Xpress / Dysregulated immune cells may cause silent inflammation after heart attack
Coronary artery disease, which is caused by plaque buildup in the arteries that supply blood to the heart, can appear stable for long periods without causing any symptoms. But the disease can become unstable at any time and ...
Medical Xpress / For the tiniest patients, new tech brings clearer MRI images
Some of medicine's smallest patients can present its biggest imaging challenges. An infant's heart can be as small as a walnut, beating rapidly inside a body that will change dramatically as the child grows. Yet much of the ...
Medical Xpress / Female gut muscles reshape to meet the demands of reproduction, preclinical study suggests
