Neural correlates of episodic memory in the Memento cohort
Stéphane Epelbaum, Vincent Bouteloup, Jean Mangin +22
IntroductionThe free and cued selective reminding test is used to identify memory deficits in mild cognitive impairment and demented patients. It allows assessing three processes:…
COGEVIS: A New Scale to Evaluate Cognition in Patients with Visual Deficiency
Claire Meyniel, Dalila Samri, Farah Stefano +9
We evaluated the cognitive status of visually impaired patients referred to low vision rehabilitation (LVR) based on a standard cognitive battery and a new evaluation tool, named t…
Disrupted core-periphery structure of multimodal brain networks in Alzheimer's Disease
Jeremy Guillon, Mario Chavez, Federico Battiston +7
In Alzheimer's disease (AD), the progressive atrophy leads to aberrant network reconfigurations both at structural and functional levels. In such network reorganization, the core a…
Ordinal Synchronization: Using ordinal patterns to capture interdependencies between time series
Ignacio Echegoyen, Victor Vera-Ávila, Ricardo Sevilla-Escoboza +2
We introduce Ordinal Synchronization () as a new measure to quantify synchronization between dynamical systems. is calculated from the extraction of the ordinal patterns r…
Detection of time reversibility in time series by ordinal patterns analysis
Johann H. Martínez, José L. Herrera-Diestra, Mario Chavez
Time irreversibility is a common signature of nonlinear processes, and a fundamental property of non-equilibrium systems driven by non-conservative forces. A time series is said to…
Reproducible evaluation of classification methods in Alzheimer's disease: framework and application to MRI and PET data
Jorge Samper-González, Ninon Burgos, Simona Bottani +13
A large number of papers have introduced novel machine learning and feature extraction methods for automatic classification of AD. However, they are difficult to reproduce because…
