We aimed at identifying the potential relationship between dynamical properties of human functional network rest and one most prominent traits personality, namely resilience. To tackle this issue, we used resting-state EEG data recorded from 45 healthy subjects. Resilience was quantified using 10-item Connor-Davidson Scale (CD-RISC). By a sliding windows approach, brain networks in each frequency band (delta, theta, alpha, beta) were constructed source-space connectivity method. Brain...
Identifying the neural substrates underlying personality traits is a topic of great interest. On other hand, it now established that brain dynamic networked system can be studied by using functional connectivity techniques. However, much current understanding personality-related differences in has been obtained through stationary analysis, which does not capture complex dynamical properties networks. In this study, we aimed at evaluating feasibility network measures to predict traits. Using...
Abstract The time course of metabolic changes was investigated in the hippocampus and parietal, rhinal frontal cortices rats from 4 to 30 months old. Samples were analysed by solid‐state high‐resolution magic angle spinning nuclear magnetic resonance method. Quantification performed with quest procedure j mrui software. Eighteen metabolites identified separated spectrum. Six them not age sensitive, particular alanine, glutamine lactate. In contrast, choline, glycerophosphocholine, myo...
Multifactorial cognitive training programs have a positive effect on cognition in healthy older adults. Among the age-sensitive domains, episodic memory is most affected. In present study, we evaluated benefits of computer-based and attention training. We targeted consciously controlled processes at encoding minimizing processing retrieval, by using more familiarity than recollection during recognition. Such an approach emphasizes prevents subjects from reinforcing their own errors. Results...
The human brain is a dynamic modular network that can be decomposed into set of modules, and its activity changes continually over time. At rest, several networks, known as Resting-State Networks (RSNs), emerge cross-communicate even at sub-second temporal scale. Here, we seek to decipher the fast reshaping in spontaneous modularity relationships with RSNs. We use Electro/Magneto-Encephalography (EEG/MEG) track dynamics three independent datasets (N = 568) healthy subjects rest. show...
The interactive effects of age and cholinergic damage were assessed behaviorally in young middle-aged rats. Rats lesioned at either 3 or 17 months by injection 192 IgG-saporin immunotoxin into the medial septum nucleus basalis magnocellularis, they then tested on a range behavioral tasks: nonmatching-to-position task T-maze, an object-recognition task, object-location open-field activity test. Depending used, only lesion effect was observed, but there no Age X Lesion interaction. Middle-aged...
Abstract Impact statement This study addresses the pressing issue of subjective cognitive decline in aging populations by investigating neurofeedback (NFB) as a potential early therapeutic intervention. By evaluating efficacy individualised NFB training compared to standard protocols, tailored each participant's EEG profile, it provides novel insights into personalised treatment approaches. The incorporation innovative elements and rigorous analytical techniques contributes advancing our...
This study aims to investigate the effects of individual differences in trait coping on brain networks at rest using electroencephalography (EEG) data. EEG recordings were processed graph theory analysis. Active and passive styles determined according factor structure Brief Coping Orientation Problems Experienced questionnaire. A structural equation modeling analysis indicated that influence strategies quality life varies strength direction. In particular, active positively correlated with...
Traumatic brain injury (TBI) is associated with a collection of physical, emotional and cognitive post complications. The background for such complex consequences may be due to number different factors, the nature these changes indicates that frontal lobes implicated. In this study we have employed gene expression arrays ontology databases search possible similarities between forms acquired injuries in order test whether molecular relationships exist pathologies. Two types experimental...
Cognitive functioning evolves throughout life. Regular practice of stimulating activities maintains or even strengthens cognitive skills. This study investigated the effects a training programme based on complex closed-ended problem solving innovative thinking. To this end, using partial least squares variance-based structural equation modeling, we first evaluated in 83 healthy adults how inhibition, flexibility, and reasoning were related to distinct dimensions Second, assessed these...
