Reservoir computing allows recovering hidden network dynamics DOI
Artem Badarin, Andrey Andreev

Published: Sept. 18, 2023

In this study, we examined reservoir computing (RC)as a tool for predicting the macroscopic dynamics of subset oscillators in network based on other parts it. As model network, utilized 300 Kuramoto with adaptation. Our results demonstrate that effectively addresses task. Additionally, similar was applied to experimental neurovisualization data and exhibited high accuracy reconstructing damaged EEG channels compared classical methods like spatial interpolation.

In the current study, we analyzed results of cognitive test (Working memory task according to Sternberg's paradigm) in patients with asthenic syndrome. To diagnose severity and type asthenia, used Multidimensional Inventory questionnaire (MFI-20). We propose a new performance metric that considers both accuracy answers their speed. Our findings demonstrate individuals more pronounced syndrome exhibit slightly higher efficiency performing tasks related working compared those less asthenia.

Features of the resting-state functional network in patients with major depressive disorder: mutual information analysis in fMRI data DOI
Vladimir Khorev, Semen Kurkin, Rositsa Paunova

et al.

Published: Sept. 18, 2023

In this work, we conducted the analysis of functional magnetic resonance imaging data in healthy subjects and patients with major depressive disorder that were obtained during experimental research when resting. The signals have undergone preprocessing filtration used to find connectivity between brain regions. Results demonstrate significant changes connections based on mutual information measure. We five significantly changed connections, four which increased more cotrol group over patients.

Published: Sept. 18, 2023

Major depressive disorder (MDD) is a common and debilitating psychiatric illness that affects millions of people worldwide. Despite advancements in the understanding its underlying mechanisms, diagnosis treatment MDD remain significant challenge. In this paper, we present an approach for classification patients with based on their functional network measures. Our results demonstrate simple Linear Discriminant Analysis achieves high accuracy (83 %) two cases: when use all network's couplings or only strongest ones.

Published: Sept. 18, 2023

Neuroscience explores the anatomy, function and development of central peripheral nervous system. Neuroscientists lately study functional brain networks to understand mental disorders like depression. Analysis these can aid in diagnosing Q-analysis, a higher-order interaction approach, may be more effective identifying regions relevant depression, compared standard paired approach. This examined networks, by using approach with Q-analysis method, depressed patients healthy subjects fMRI data. Results indicated fewer weaker interactions controls. Modularity clustering were also reduce These findings highlight importance studying for understanding
