Speech understanding, watching a movie, listening to music etc., requires perception of the temporal order at least two incoming events. A history performing these tasks may be reflected in spontaneous brain activity. Here, we examined relationship between complexity (temporal dynamics) resting‑state EEG (rsEEG) signal, assessed using multivariate MultiScale Entropy (mMSE) algorithm, and event ordering, indexed by visual threshold (TOT), i.e., minimum duration necessary correctly identify before‑after relation stimuli. Healthy adolescents young adults performed psychophysical task measuring TOT underwent an eyes‑closed rsEEG study. The features mMSE vectors, namely area under curve (AUC) that represents total signal complexity, as well MaxSlope AvgEnt, corresponding entropy fine‑ coarse‑grained timescales, respectively, were obtained for central (midline), anterior, middle posterior channel sets. greater AUC AvgEnt values central, left right areas, higher region, TOT. most significant relationships found midline electrodes (Fz, Cz, Pz, Oz). There no correlations To best our knowledge, this is first study demonstrating associated with stimuli presented rapid succession. Our findings indicate low coarse levels are beneficial judgments.

Background: Observation, execution, and imitation of target actions based on mirror neuron network (MNN) have become common physiotherapy strategies. Electrical stimulation (ES) is a intervention to improve muscle strength motor control in rehabilitation treatments. It possible enhance MNN’s activation by combining execution (ME) (MI) with ES simultaneously. This study aims reveal whether could impact cortical during ME MI. Methods: We recruited healthy individuals assigned them randomly the group (CG) or experiment (EG). Participants EG performed MI tasks ES, while participants CG same two sham ES. utilized functional near-infrared spectroscopy (fNIRS) detect brain MNN without randomized block design paradigm was designed. Descriptive analysis oxy-hemoglobin (HbO) deoxy-hemoglobin (HbR) were used show hemoglobin (Hb) concentration changes after different event onsets both EG, linear mixed-effects model (LMM) HbO data employed analyze effect MNN. Results: A total 102 adults 72 participants’ analysed final report. The averaged Hb showed that increased HbR decreased most regions groups. LMM results can significantly inferior frontal gyrus, middle precentral gyrus MI, supplementary area, parietal lobule, superior temporal gyri activation, but statistical significance. Although did not reach significance ME, still positive effects overall activations. Conclusions: In this study, we present potential novel approaches combines strategies low-frequency activation.

The extent to which brain responses are less distinctive across varying cognitive loads in older adults is referred as neural dedifferentiation. Moment-to-moment signal variability, an emerging indicator, reveals not only the adaptability of individual's inter-individual trait, but also allocation resources within individual due ever-changing task demands, thus shedding novel insight into process However, how modulation intra-individual variability reflects behavioral differences related cognitively demanding tasks remains unclear. In this study, we employed functional near-infrared spectroscopy (fNIRS) imaging capture signals, was quantified by standard deviation, during both resting state and n-back (n=1, 2, 3) 57 healthy adults. Using multivariate Partial Least Squares (PLS) analysis, found that fNIRS increased from with working memory load We further confirmed greater generally supported faster more stable response time 2- 3-back conditions. level analysis showed up-modulation loads, its accuracy decreases mean increases, suggesting a may reflect decreased efficiency information processing. Taken together, our findings offer new insights nature inter- index distinct theoretical constructs.
