Assortative mixing in micro-architecturally annotated brain connectomes
Nature Communications, 2023 The wiring of the brain connects micro-architecturally diverse neuronal populations, but the conventional graph model, which encodes macroscale brain connectivity as a network of nodes and edges, abstracts away the rich biological detail of each regional

Egas Moniz: 90 years (1927-2017) from cerebral angiography [PDF]
, 2017 In June 2017 we celebrate the 90th anniversary of the pioneer discovery of cerebral angiography, the seminal imaging technique used for visualizing cerebral blood vessels and vascular alterations as well as other intracranial disorders.

Imaging glutathione depletion in the rat brain using ascorbate-derived hyperpolarized MR and PET probes. [PDF]
, 2018 Oxidative stress is a critical feature of several common neurologic disorders. The brain is well adapted to neutralize oxidative injury by maintaining a high steady-state concentration of small-molecule intracellular antioxidants including glutathione in

Fast Multi-Task SCCA Learning with Feature Selection for Multi-Modal Brain Imaging Genetics [PDF]
, 2018 Brain imaging genetics studies the genetic basis of brain structures and functions via integrating both genotypic data such as single nucleotide polymorphism (SNP) and imaging quantitative traits (QTs).

NeuroImage, 2004 We describe how implicit surface representations can be used to solve fundamental problems in brain imaging. This kind of representation is not only natural following the state-of-the-art segmentation algorithms reported in the literature to extract the different brain tissues, but it is also, as shown in this paper, the most appropriate one from the ...
