Characterization of sustained BOLD activation in the rat barrel cortex and Neurochemical consequences

Rolf Gruetter, Lijing Xin, Nathalie Just, Hanne Frenkel

To date, only a couple of functional MR spectroscopy (fMRS) studies were conducted in rats. Due to the low temporal resolution of 1H-MRS techniques, prolonged stimulation paradigms are necessary for investigating the metabolic outcome in the rat brain duri ...

Alteration of brain glycogen turnover in the conscious rat after 5h of prolonged wakefulness

Rolf Gruetter, Pierre Magistretti, Bernard Lanz, Jean-Marie Petit, Hanne Frenkel

Although glycogen (Glyc) is the main carbohydrate storage component, the role of Glyc in the brain during prolonged wakefulness is not clear. The aim of this study was to determine brain Glyc concentration ([]) and turnover time (tau) in euglycemic conscio ...

Selective Resonance Suppression H-1-[C-13] NMR Spectroscopy With Asymmetric Adiabatic RF Pulses

Rolf Gruetter, Lijing Xin, Hanne Frenkel

Despite obvious improvements in spectral resolution at high magnetic field, the detection of C-13 labeling by H-1-[C-13] NMR spectroscopy remains hampered by spectral overlap, such as in the spectral region of H-1 resonances bound to C3 of glutamate (Glu) ...
