fMRI is based on the same technology asmagnetic resonance imaging(MRI) -- a noninvasive test that uses a strong magnetic field and radio waves to create detailed images of the body. But instead of creating images of organs and tissues like MRI, fMRI looks atbloodflow in the brain to detect...
If we practice poorly and do not correct our mistakes, we will myelinate those axons, increasing the speed and strength of those signals – which does us no good. The takeaway: practicing skills over time causes those neural pathways to work better in unison via myelination. To improve...
However, the skull blocks a lot of the electrical signal, and it distorts what does get through. To get a higher-resolution signal, scientists can implant electrodes directly into the brain tissue itself, or on the surface of the brain, beneath the skull. This allows for much more direct ...

ARIA is seen from magnetic resonance imaging (MRI) scans of the brain and may present as temporary swelling or small spots of bleeding in or on the brain surface. ARIA does not usually cause symptoms, although serious, life-threatening and fatal events can rarely occur. The most common side...
Studies have been done to try to determine the chemical makeup that might explain why the prairie vole forms this lifelong, monogamous relationship when its very close relative, the montane vole, does not. According to studies by Larry Young, a social attachment researcher at Emory University, ...

Functional MRI is providing further information on the links between acupuncture points and the activation of specific regions of the brain. Presently, models of the neurophysiologic mechanisms of acupunctur...
