TL;DR: The overall findings provide direct evidence of declined mitochondrial functions and altered NAD homeostasis that accompany the normal aging process and elucidate the merits and potentials of this new NAD assay for noninvasively studying the intracellular NAD metabolism and redox state in normal and diseased human brain or other organs in situ.

TL;DR: The functional activation in cortical motor areas during movement of the dominant and nondominant hand in groups of right-handed and left-handed subjects and found that use of the Dominant hand was associated with a greater volume of activation in the contralateral motor cortex.

TL;DR: By controlling the temporal relation of input tasks, it is possible to study temporal evolution of certain neural events at the time scale of their evoked electrical activity by noninvasive fMRI methodology.

TL;DR: While the use of very high magneticfields such as 7 Tesla in human studies is still in its infancy, the datagathered to date suggest that there are signi-cant gains for spectroscopy studies in general and some of these achievements relevant to high magnetic fiElds are reviewed in article.

TL;DR: Temporal progression of the RF field indicates that the standing wave and associated dielectric resonance occurring in a pure water phantom near 300 MHz is greatly dampened in the human head due to the strong decay of the electromagnetic wave.
