With a background in magnetic resonance physics, Rebecca spent her PhD studies developing advanced functional magnetic resonance imaging techniques to observe the changes in brain activity, functional connectivity and cerebral perfusion caused by the onset of disease or the administration of a drug. More specifically, she conducted a study into the effect of the peripherally acting beta-blocker, Nadolol, on the arterial spin labelling (ASL) perfusion and blood-oxygen level dependent (BOLD) fMRI response to emotional visual stimuli.
Rebecca is now conducting a study using the functional neuroimaging technique of near-infrared spectroscopy (NIRS) in combination with fMRI to measure activation patterns in the auditory network in response to non-auditory sensory stimuli in profoundly deaf individuals, and to investigate whether these patterns change with cochlear implant use.
