Research Abstract

We performed the same fMRI(functional Magnetic Resonance Imaging) study for different head positions by tilting the volunteer's head and showed that the activation area is strongly influenced by the orientation of the draining vein from the activation focus where the neurons are activated. And we showed that the MR signal from the cortex capillary bed contains signal from interstitial fluid which may depend on oxygen concentration in tissue, and that the sum of the BOLD(Blood oxygenation level-dependent) signals from the activation focus correlates quantitatively with the sum of the peak-to-peak amplitude of the evoked potential responses.
