Can we enlist substitute genes to fight muscular dystrophy
...dystrophy. Dystrophin and utrophin perform similar tasks at the neuromuscular junction where nerve cells meet muscle tissue and studies have shown that utrophin over-production reverses the symptoms of muscular dystrophy in mice, said Tejvir S.

...nal magnetic brain imaging (fMRI) scans from these tasks were compared with images from 22 adults (an average of 25 years old) who had completed similar tasks. FMRI images reveal which brain regions are actively involved in different tasks.
