Neurofeedback (NF) is a biofeedback technique that teaches individuals self-control of brain functions by measuring activations and providing an online feedback signal to modify emotional, cognitive, behavioral functions. NF approaches typically rely on single modality, such as electroencephalography (EEG-NF) or imaging technique, functional magnetic resonance (fMRI-NF). The introduction simultaneous EEG-fMRI tools has opened up the possibility combining high temporal resolution EEG with spatial fMRI, thereby increasing accuracy NF. However, only few studies have actively combined both techniques. In this study, we conducted systematic review EEG-fMRI-NF (N = 17) identify potential effectiveness non-invasive treatment for neurological conditions. revealed lack homogeneity among studies, including sample sizes, acquisition methods in terms simultaneity two procedures (unimodal EEG-NF fMRI-NF), therapeutic targets field, number sessions. Indeed, because most are based session NF, it difficult draw any conclusions regarding efficacy Therefore, further research needed fully understand non-clinical clinical EEG-fMRI-NF.

Interoception can be described as the ability to perceive inner body sensations and it is different between biological sex. However, no previous research correlated this with brain functional connectivity (FC) males females. In study, we used resting-state magnetic resonance imaging investigate FC of networks involved in interoception among females a sample healthy volunteers matched for age. total, 67 participants (34 females, mean age 44.2; 33 males, 37.2) underwent MRI session completed Self-Awareness Questionnaire (SAQ) that tests interoceptive awareness. To assess effect sex on scores obtained SAQ performed multivariate analysis variance. A whole-brain seed-to-seed was conducted correlation score FC, then test differences covariate. MANOVA revealed significant difference higher values second ones. Also, correlations Salience network fronto-temporo-parietal areas have been detected, sharp prevalence female. These results support idea female advantage attention toward sensations, suggesting common inter-network concur create sense self.

Total sleep deprivation (TSD) leads to cognitive decline; however, the neurophysiological mechanisms underlying resting-state electroencephalogram (EEG) changes after TSD remain unclear. In this study, 42 healthy adult participants were subjected 36 h of (36 TSD), and EEG data recorded at baseline, 24 (24 TSD. The analysis TSD, using source localization analysis, power spectrum functional connectivity revealed a decrease in alpha-band significant increase delta-band impaired default mode network, precuneus, inferior parietal lobule. cortical activities lobule, superior lobule significantly reduced, but no difference was found between groups.

Patients with Mild Cognitive Impairment (MCI) may exhibit poorer performance in visuomotor tasks than healthy individuals, particularly under conditions high cognitive load. Few studies have examined reaching movements MCI and did so without assessing susceptibility to distractor interference. This proof-of-concept study analyzed the kinematics of visually guided towards a target dot placed along participants' midsagittal/reaching axis. Movements were performed visual (flanker) at various distances from Participants instructed avoid "touching" flanker during movement execution. The whole sample included 11 patients due Alzheimer's disease, 10 older adults, 12 young all right-handed. whose trajectories deviated significantly away flanker, especially when it was 1 mm away, less consistent controls. Also, our results suggest that trajectory curvature discriminate between adults. analysis interference enhance diagnosis MCI, underscoring need for multidimensional assessments incorporating both motor domains.

Using tools effectively is a fundamental human ability. Besides the proper recall of semantic knowledge, application mechanical problem solving strategies allows one to execute tool-related tasks properly. Past fMRI studies have shown mainly left-lateralized network, including ventral, ventro-dorsal, and dorso-dorsal streams while using familiar with access information. However, what degree network recruited when applying handle novel remains unclear. An event-related study 22 participants was conducted. During scanning, had manipulate tools, function which they could infer by solving. Brain activity measured during actual tool use selection, both planning execution phase. Similar brain activation selection be observed, ranging from left-hemispheric inferior parietal frontal regions in ventro-dorsal stream lack ventral activation.

Academic institutions are increasingly adopting active learning methods to enhance educational outcomes. Using functional magnetic resonance imaging (fMRI), we investigated neurobiological differences between and traditional lecture-based approaches in university physics education. Undergraduate students enrolled an introductory course underwent fMRI session before after a 15-week semester. Coactivation pattern (CAP) analysis was used examine the temporal dynamics of brain states across different cognitive contexts, including conceptual reasoning, knowledge retrieval, rest. CAP results identified seven distinct states, with contributions from frontoparietal, somatomotor, visuospatial networks. Among students, associated increased engagement somatomotor network, supporting embodied cognition framework, while demonstrated stronger consistent observational learning. These findings suggest significant neural restructuring over semester learning, instructional preferentially modulating patterns dynamics.

Our propensity to materiality, which consists in using, making, creating, and passing on technologies, has enabled us shape the physical world according our ends. To explain this proclivity, scientists have calibrated their lens either low-level skills such as motor cognition or high-level language social cognition. Yet, little been said about intermediate-level cognitive processes that are directly involved mastering is, technical We aim focus intermediate level for providing new insights into neurocognitive bases of human materiality.

Abstract Action tool knowledge can be assessed mainly with two kinds of tasks: tool-tool and hand-tool compatibility tasks. While these tasks are used to assess action knowledge, recent data showed striking dissociations between in brain-damaged patients. In this study, we explored the neuropsychological (Experiment 1; 60 patients) potential cognitive mechanisms engaged during 2; 52 healthy participants). Finally, also reanalyzed fMRI investigate neural bases 3; 34 The three experiments provide convergent arguments by showing that both share common core computations supported a left-lateralized brain network, but task engages regions outside network is explained visual imagery while rather motor imagery.
