Cerebral stiffness changes during visual stimulation: Differential physiological mechanisms characterized by opposing mechanical effects

Cerebral stiffness changes during visual stimulation: Differential physiological mechanisms characterized by opposing mechanical effects

We performed functional intrinsic Magnetic Resonance Elastography (fiMRE) as well as Time of Flight angiography and BOLD fMRI on 7 healthy human subjects to monitor shear stiffness and arterial dilation during periods of prolonged visual stimulation. FiMRE activation with increased stiffness was obs...
