2026 Publications

A graphical abstract mapping an fMRI study cohort into three participant groups: misophonia only, misophonia with hyperacusis, and healthy controls. Arrows trace the data pipeline through a resting-state fMRI scanner, functional connectivity maps, and machine learning classifiers to isolate dysregulations in connectivity across control, salience, and motor networks.

2025 Publications

A graphical abstract mapping a brain imaging study of tinnitus and hearing loss using voxel-based morphometry (VBM). Under the participants section, a flowchart indicates a cohort of N=100 broken down into tinnitus and control groups, further subdivided by normal hearing or hearing loss. Under the results section, two brain diagrams display localized structural effects: the top brain highlights gray matter volume changes associated with the effects of hearing loss in the superior temporal gyrus, planum polare, and inferior insula, and the bottom brain highlights changes associated with the effects of tinnitus in the central operculum and posterior insula. A separate box outlines conclusions regarding tinnitus severity, noting a positive correlation between severity and gray matter volume in the planum polare.

2022 Publications

A graphical abstract mapping a positron emission tomography (PET) brain imaging study evaluating the efficacy of hearing aids for tinnitus therapy. Under the participants section, a flowchart shows two groups: 19 individuals with tinnitus and hearing loss, and 14 individuals with hearing loss serving as controls. An arrow indicates a 6-month period of auditory rehabilitation. Under the results section, a diagram highlights regional changes in glucose metabolism following rehabilitation, showing an increase in uptake in the rectus gyrus, temporal lobe, and hippocampus, alongside a decrease in uptake in the cerebellum and inferior parietal lobe.

2021 Publications

A graphical abstract mapping a brain imaging study of tinnitus severity using arterial spin labeling (ASL) cerebral blood flow (CBF). Under the participants section on the left, a flowchart breaks down a cohort into 60 tinnitus patients and 31 control subjects. Arrows point toward a central diagram showing a sagittal brain view with blue and red arrows representing cerebral blood flow. To the right, a bar graph compares cerebral blood flow between controls and tinnitus patients, showing decreased perfusion in the tinnitus group. An adjacent sagittal brain diagram highlights the locations of the precuneus and posterior cingulate cortex, with an arrow pointing to a separate line graph that demonstrates a negative correlation between regional blood flow and tinnitus severity.

2020 Publications

A graphical abstract illustrating a conceptual model of cognitive and perceptual resource engagement by a tinnitus signal. On the left, an icon labeled tinnitus signal sends divergent pathways to a diagram of a human brain on the right. Blue lines represent cognitive resources engaged by the tinnitus signal, which map to the ventrolateral prefrontal cortex (vlPFC), anterior cingulate cortex (ACC), orbitofrontal cortex (OFC), and precuneus (Prec). Orange lines represent perceptual resources engaged by the tinnitus signal, mapping to the auditory cortex (AC), occipital cortex (OC), and fusiform gyrus (FFG). A legend in the upper left defines the color-coded blue pathway as cognitive resources engaged by tinnitus signal, and the orange pathway as perceptual resources engaged by tinnitus signal.
