Medical Xpress / Mapping pre-myelinating oligodendrocytes: New mouse line links neuronal activity to cell survival

Nerve fibers in the brain and spinal cord are wrapped in an insulating sheath known as myelin. For a long time, this barrier, which is essentially the brain's white matter, was believed to serve the main function of speeding ...

Medical Xpress / 40% of MRI signals do not correspond to actual brain activity, study suggests

For almost three decades, functional magnetic resonance imaging (fMRI) has been one of the main tools in brain research. Yet a new study published in Nature Neuroscience fundamentally challenges the way fMRI data have so ...
