ABSTRACT Long‐term training enables professional athletes to develop concentrated and efficient neural network organizations for specific tasks. This study used functional near‐infrared spectroscopy investigate task performance, brain characteristics, their relationships in footballers during sport‐specific motor‐cognitive processes. Twenty‐four (athlete group, with 18 remaining of good signal quality) 20 non‐footballers (control 16 remaining) completed four tasks: a single (trigger buttons corresponding the appearance direction teammates kicking actions), an N‐back task, dual digit task. Brain activation, connectivity (FC), lateralization were calculated, correlation behavioral indicators was analyzed. Results showed that reaction times shorter across all The activation value right dorsolateral prefrontal cortex (DLPFC) decreased compared resting state athlete group. values regions (except left primary sensory task), DLPFC (dual premotor & supplementary motor area (left PMC SMA, task) significantly lower group than control Footballers exhibited higher interhemispheric FC tasks, greater leftward bias between (PFC) ‐left SMA within PFC region positively correlated accuracy better performance less impact from load, central energy consumption sensory‐motor execution, indicating more state.

While still relatively rare, longitudinal hyperscanning studies are exceptionally valuable for documenting changes in inter-brain synchrony, which may turn underpin how behaviors develop and evolve social settings. The generalizability ecological validity of this experimental approach hinges on the selected imaging technique being mobile–a requirement met by functional near-infrared spectroscopy (fNIRS). fNIRS has most frequently been used to examine development synchrony behavior child-parent dyads. In position paper, we contend that dedicating attention intergenerational stands benefit fields cognitive neuroscience more broadly. We argue is particularly relevant understanding neural mechanisms underpinning dynamics, potentially benchmarking progress psychological interventions, many situated contexts. line with our position, highlight areas research stand be enhanced mobile devices, describe challenges arise from measuring across generations real world, offer potential solutions.

Objective Numerous studies suggest that hypnosis has significant potential in mental health and cognitive disorder treatments. However, the mechanisms by which influences brain activity functional network connectivity remain unclear.

With the growing interest in establishing brain-based biomarkers for precision medicine, there is a need noninvasive, scalable neuroimaging devices that yield valid and reliable metrics. Kernel's second-generation Flow2 Time-Domain Functional Near-Infrared Spectroscopy (TD-fNIRS) system meets requirements of noninvasive neuroimaging, uses validated modality to measure brain function. In this work, we investigate test-retest reliability (TRR) set metrics derived from recordings. We adopted repeated-measures design with 49 healthy participants, quantified TRR over multiple time points different headsets—in experimental conditions including resting state, sensory, cognitive task. Results demonstrated high state features hemoglobin concentrations, head tissue light attenuation, amplitude low frequency fluctuations, functional connectivity. Additionally, passive auditory Go/No-Go inhibitory control tasks each exhibited similar activation patterns across days. Notably, areas highest were regions during task, right prefrontal consistent prior literature. This study underscores Flow2-derived metrics, supporting its potential actualize vision using diagnosis, treatment selection monitoring neuropsychiatric neurocognitive disorders.

Intraventricular hemorrhage (IVH) is a common neurological injury following very preterm birth. Resting-state functional connectivity (RSFC) using magnetic resonance imaging (fMRI) associated with severity; yet, fMRI impractical for use in intensive care settings. Functional near-infrared spectroscopy (fNIRS) measures RSFC through cerebral hemodynamics and has greater bedside accessibility than fMRI. We evaluated neonates IVH fNIRS at term-equivalent age, compared between healthy newborns those IVH. Sixteen born were scanned fNIRS. Additionally, fifteen In preterms IVH, maps Euclidean Jaccard distances. The severity of relation to fNIRS-RSFC strength was examined generalized linear models. showed good correspondence. Connectivity significantly lower (p-value = 0.023) infants mild 0.026) moderate/severe potential be new tool assessing brain monitoring hemodynamics, as well promising biomarker infants.
