LPI research on COVID-19

[25 May 2020]

The first LPI article about the psychological impact of the COVID-19 confinement has been published. This article has been made in collaboration with the Department of Psychology of the University of Valladolid. The main finding was that students from Arts & Humanities and Social Sciences and Law areas showed higher psychological impact, especially compared to the students from the Engineering & Architecture field (click on the title of the article for more highlights). The article is freely available until 11 July in the following link: https://doi.org/10.1016/j.psychres.2020.113108

New dMRI methodology to calculate q-space measures

[11 Mar 2020]

A new paper entitled Micro-structure diffusion scalar measures from reduced MRI acquisitions has been published in PLOS ONE. The work is written by member of the LPI (Santiago Aja-Fernández, Rodrigo de Luis-García, Antonio Tristán-Vega)  in collaboration with reserachers from AGH University of Science and Technology, Krakow, Poland (Tomasz Pieciak) and CUBRIC, University of Cardiff, UK Maryam Afzali, Malwina Molendowska). In the work, we propose a method to effectively calculate apparent RTOP, RTPP, and RTAP from single shell diffusion MRI. The method achieves closed-form expressions and a computationally efficient and robust implementation. Methods are implemented in MATLAB and they will be publicly release soon. We can submitted them no upon request.  [Link to paper]

White matter changes in migraine

[07 Jan 2020]

A new paper, White matter changes in chronic and episodic migraine: a diffusion tensor imaging study, written by Álvaro Planchuelo-Gómez, Santiago Aja-Fernández and Rodrigo de Luis-García, in colaboration with the Headache Unit and the Deparment of Radiology of the Clinical Hospital of Valladolid, has been published in the Journal of Headache and Pain. In this article, global white matter differences between chronic and episodic migraine have been found for the first time using Diffusion Tensor Imaging (DTI) measures and Tract-Based Spatial Statistics (TBSS). Our findings suggest axonal integrity impairment in the first months of chronic migraine, with respect to episodic migraine, and a posterior set of maladaptive white matter plastic changes in chronic migraine.
