Experience of tinnitus in adults who have severe-to-profound hearing loss: A scoping review (2022)
Journal Article
Alzahrani, L., Sereda, M., Chamouton, C. S., Haider, H., Dewey, R. S., & Hoare, D. J. (2022). Experience of tinnitus in adults who have severe-to-profound hearing loss: A scoping review. Frontiers in Neurology, 13, Article 1004059. https://doi.org/10.3389/fneur.2022.1004059

Background: Tinnitus is defined as the subjective perception of sound in the absence of an external stimulus, and tinnitus disorder becomes relevant when it is associated with emotional distress, cognitive dysfunction, and/or autonomic arousal. Heari... Read More about Experience of tinnitus in adults who have severe-to-profound hearing loss: A scoping review.

Background:Brain magnetic resonance imaging in patients with cochlear implants (CIs) is impacted by image artefacts.Hypothesis:The optimal positioning of the CI to minimize artefacts is unknown. This study aimed to characterize the dependence of the... Read More about Parametric Assessment of the Effect of Cochlear Implant Positioning on Brain MRI Artefacts at 3 T.

Comparison of continuous sampling with active noise cancelation and sparse sampling for cortical and subcortical auditory functional MRI (2021)
Journal Article
Dewey, R. S., Hall, D. A., Plack, C. J., & Francis, S. T. (2021). Comparison of continuous sampling with active noise cancelation and sparse sampling for cortical and subcortical auditory functional MRI. Magnetic Resonance in Medicine, 86(5), 2577-2588. https://doi.org/10.1002/mrm.28902

Purpose Detecting sound-related activity using functional MRI requires the auditory stimulus to be more salient than the intense background scanner acoustic noise. Various strategies can reduce the impact of scanner acoustic noise, including “sparse...

Qualitative and quantitative assessment of magnetic vestibular stimulation in humans (2020)
Journal Article
Dewey, R. S., Gomez, R., Degg, C., Baguley, D. M., & Glover, P. (2020). Qualitative and quantitative assessment of magnetic vestibular stimulation in humans. Journal of Vestibular Research, 30(6), 353-361. https://doi.org/10.3233/VES-201538

The sensation of phantom motion or exhibition of bodily sway is often reported in the proximity of an MR scanner. It is proposed that the magnetic field stimulates the vestibular system. There are a number of possible mechanisms responsible, and the... Read More about Qualitative and quantitative assessment of magnetic vestibular stimulation in humans.

The association between subcortical and cortical fMRI and lifetime noise exposure in listeners with normal hearing thresholds (2019)
Journal Article
Dewey, R. S., Francis, S. T., Guest, H., Prendergast, G., Millman, R. E., Plack, C. J., & Hall, D. A. (2020). The association between subcortical and cortical fMRI and lifetime noise exposure in listeners with normal hearing thresholds. NeuroImage, 204, https://doi.org/10.1016/j.neuroimage.2019.116239

© 2019 In animal models, exposure to high noise levels can cause permanent damage to hair-cell synapses (cochlear synaptopathy) for high-threshold auditory nerve fibers without affecting sensitivity to quiet sounds. This has been confirmed in several... Read More about The association between subcortical and cortical fMRI and lifetime noise exposure in listeners with normal hearing thresholds.

Evidence from functional neuroimaging studies suggests that the auditory cortex can become more responsive to visual and somatosensory stimulation following deafness, and that this occurs predominately in the right hemisphere. Extensive cross-modal p... Read More about Cortical cross-modal plasticity following deafness measured using functional near-infrared spectroscopy.
