The caloric test was performed in healthy volunteers during the BOLDfMRI scanning.
2
Most studies involving BOLDfMRI in basic neuroscience research are conducted with anesthetized animals.
3
The mechanisms of neurovascular coupling underlying generation of BOLDfMRI signals remain incompletely understood.
4
These results suggest that purinergic signaling plays a significant role in generation of BOLDfMRI signals.
5
Our data indicates that the contribution of venous oxygenation change to BOLDfMRI is dominant for short stimulations.
6
Resting state BOLDfMRI was measured at the height of her illness and 18 weeks following discharge from hospital.
7
However, TMPAP catalytic activity markedly reduced the magnitude of BOLDfMRI responses triggered in the SSFP region by forepaw stimulation.
8
Visualization of mTL memory activation with BOLDfMRI is complicated by the presence of static susceptibility gradients in this region.
9
At very high magnetic fields, GE BOLDfMRI is expected to contain nonspecific contributions and behave differently than HSE fMRI data.
10
Similarly, BOLDfMRI responses measured at 9.4 T were largest at a frequency of 10 Hz.
11
This study investigates neural and hemodynamic activity through a combination of experiments comprising BOLDfMRI, optical calcium recordings and ASL in vivo.
12
However, the ability of BOLDfMRI to map cortical columnar structures is highly controversial, as the ultimate functional specificity of BOLD remains unknown.
13
BOLDfMRI experiments, using visually paced finger-tapping paradigms, showed no detrimental effect of the acoustic noise reduction strategy on temporal noise levels and t scores.
