Magnetic resonance spectroscopy of the living brain is described. It is based on the same physics as magnetic resonance imaging, but instead of images based on the signal from tissue water, it measures specific compounds in the brain, currently numbering some two dozen. Being almost entirely non-invasive, it is well-suited for longitudinal and human studies of both normal function and disease p...

We study the phenomenon of spatiotemporal stochastic resonance (STSR) in a chain of diffusively coupled bistable oscillators. In particular, we examine the situation in which the global STSR response is controlled by a locally applied signal and reveal a wave-front propagation. In order to deepen the understanding of the system dynamics, we introduce, on the time scale of STSR, the study of the...

Synopsis: This presentation will provide an overview of recent developments in Magnetic Resonance Spectroscopy research. An improved acquisition schemes as well discussion tools and software for analysis be given. The talk also discussed on the clinical use MRS, its limitations, how this could addressed.

BIRD's eye view: Adding periodic BIRD J-refocusing (BIRD=bilinear rotation decoupling) to data acquisition in an HSQC experiment causes broadband homonuclear decoupling, giving a single signal for each proton chemical shift. This pure shift method improves both resolution and signal-to-noise ratio, without the need for special data processing.

The precise role of non-conventional hydrogen bonds such as the C-H⋅⋅⋅O interaction in influencing the conformation of small molecules remains unresolved. Here we survey a series of β-turn mimetics using X-ray crystallography and NMR spectroscopy in conjunction with quantum calculation, and conclude that favourable torsional and electronic effects are important for the population of states with...

A detailed 13C NMR study of thiostrepton and two series of thiopeptin components is consistent with their proposed structures and allows many unequivocal assignments to be made.

Ultrafast (UF) NMR spectroscopy is an approach that yields 2D spectra in a single scan. This methodology has become a powerful analytical tool that is used in a large array of applications. However, UF NMR spectroscopy still suffers from an intrinsic low sensitivity, and from the need to compromise between sensitivity, spectral width, and resolution. In particular, the modulation of signal inte...
