Neuromelanin-MRI to Quantify and Track Nigral Depigmentation in Parkinson's Disease: A Multicenter Longitudinal Study Using Template-Based Standardized Analysis (2022)
Journal Article

Background: Clinical diagnosis and monitoring of Parkinson's disease (PD) remain challenging because of the lack of an established biomarker. Neuromelanin-magnetic resonance imaging (NM-MRI) is an emerging biomarker of nigral depigmentation indexing...

Brain perfusion patterns are altered in chronic knee pain: a spatial covariance analysis of arterial spin labelling MRI (2020)
Journal Article

Chronic musculoskeletal pain is a common problem globally. Current evidence suggests that maladapted central pain pathways are associated with pain chronicity, for example, in postoperative pain after knee replacement. Other factors such as low mood,...

FU-Net: Multi-class Image Segmentation Using Feedback Weighted U-Net (2019)
Book Chapter

© 2019, Springer Nature Switzerland AG. In this paper, we present a generic deep convolutional neural network (DCNN) for multi-class image segmentation. It is based on a well-established supervised end-to-end DCNN model, known as U-net. U-net is firs... Read More about FU-Net: Multi-class Image Segmentation Using Feedback Weighted U-Net.

Relationship between neuromelanin and dopamine terminals within the Parkinson’s nigrostriatal system (2019)
Journal Article

© 2019 The Author(s). All rights reserved. Parkinson's disease is characterized by the progressive loss of pigmented dopaminergic neurons in the substantia nigra and associated striatal deafferentation. Neuromelanin content is thought to reflect the... Read More about Relationship between neuromelanin and dopamine terminals within the Parkinson’s nigrostriatal system.

Coordinate based meta-analysis of motor functional imaging in Parkinson's: disease-specific patterns and modulation by dopamine replacement and deep brain stimulation (2019)
Journal Article

Objective To investigate factors affecting the pattern of motor brain activation reported in people with Parkinson’s (PwP), aiming to differentiate disease-specific features from treatment effects. Methods A co-ordinate-based-meta-analysis (CBMA...

Lifespan pigmentation changes of the substantia nigra detected by neuromelanin-sensitive MRI (2018)
Journal Article
Xing, Y., Sapuan, A., Dineen, R., & Auer, D. P. (2018). Lifespan pigmentation changes of the substantia nigra detected by neuromelanin-sensitive MRI. Movement Disorders, 33(11), 1792-1799. https://doi.org/10.1002/mds.27502

Background: Neuromelanin is a pigment with strong iron-chelating properties preferentially found in dopaminergic neurons of the substantia nigra, pars compacta (SNpc). Parkinson's disease is characterized by pronounced, MRI detectable neuromelanin lo... Read More about Lifespan pigmentation changes of the substantia nigra detected by neuromelanin-sensitive MRI.

Parkinson's disease related signal change in the nigrosomes 1–5 and the substantia nigra using T2* weighted 7T MRI (2018)
Journal Article

Improved markers for the progression of Parkinson's disease (PD) are required. Previous work has proven that iron dependent MRI scans can detect the largest Nigrosome (N1) within the substantia nigra (SN) pars compacta and changes in PD. Histopatholo...

The influence of spatial pattern on visual short-term memory for contrast (2014)
Journal Article
Xing, Y., Ledgeway, T., McGraw, P. V., & Schluppeck, D. (2014). The influence of spatial pattern on visual short-term memory for contrast. Attention, Perception, and Psychophysics, 76(7), https://doi.org/10.3758/s13414-014-0671-x

Several psychophysical studies of visual short-term memory (VSTM) have shown high-fidelity storage capacity for many properties of visual stimuli. On judgments of the spatial frequency of gratings, for example, discrimination performance does not dec... Read More about The influence of spatial pattern on visual short-term memory for contrast.

Most studies of the early stages of visual analysis (V1-V3) have focused on the properties of neurons that support processing of elemental features of a visual stimulus or scene, such as local contrast, orientation, or direction of motion. Recent evi... Read More about Decoding working memory of stimulus contrast in early visual cortex.
