Journal ArticleDOI

Natalie J. Forde,Stefani O'Donoghue,Cathy Scanlon,Cathy Scanlon,Louise Emsell,Louise Emsell,Chris Chaddock,Alexander Leemans,Ben Jeurissen,Gareth J. Barker,Dara M. Cannon,Robin M. Murray,Colm McDonald +12 more
TL;DR: Structural brain network analysis is used to investigate connectivity abnormalities in multiply affected BP type I families, to assess the utility of dysconnectivity as a biomarker and its endophenotypic potential and no differences between groups were found.
Journal ArticleDOI
In vivo diffusion tensor imaging (DTI) of brain subdivisions and vocal pathways in songbirds.
Geert De Groof,Marleen Verhoye,Vincent Van Meir,Ilse Tindemans,Alexander Leemans,Anne-Marie Van Der Linden +5 more
TL;DR: In vivo Diffusion-Tensor MRI (DT-MRI or DTI) is explored to visualize the distinct, concentrated connections of the SCS in the brain of the starling (Sturnus vulgaris).
Journal ArticleDOI
Intravoxel incoherent motion modeling in the kidneys: Comparison of mono-, bi-, and triexponential fit
Sophie Jacobine van Baalen,Alexander Leemans,Pieter Dik,Marc R. Lilien,Bernard ten Haken,Martijn Froeling +5 more
TL;DR: To evaluate if a three‐component model correctly describes the diffusion signal in the kidney and whether it can provide complementary anatomical or physiological information about the underlying tissue, three-component models are evaluated.
Journal ArticleDOI
Small vessel disease and cognitive impairment: The relevance of central network connections.
Yael D. Reijmer,Panagiotis Fotiadis,Giovanni Piantoni,Gregoire Boulouis,Kathleen Kelly,Mahmut Edip Gurol,Alexander Leemans,Michael O'Sullivan,Steven M. Greenberg,Anand Viswanathan +9 more
TL;DR: It is suggested that the centrality of network connections, and thus their contribution to global network efficiency, appears to be relevant for understanding the relationship between SVD and cognitive impairment.
Journal ArticleDOI
Anatomical integration and rich-club connectivity in euthymic bipolar disorder.
Stefani O'Donoghue,Liam Kilmartin,Denis O'Hora,Denis O'Hora,Louise Emsell,Camilla Langan,Shane McInerney,Natalie J. Forde,Alexander Leemans,Ben Jeurissen,Gareth J. Barker,Peter McCarthy,Donald M. Cannon,Christine McDonald +13 more
TL;DR: Graph theory analysis presents a thorough investigation of topological features of connectivity in euthymic bipolar disorder, providing further neuroanatomically specific evidence for distributed dysconnectivity as a trait feature of BD.
