Railway travel is an eco-friendly means of transportation, and passengers are spending increasing amounts time on trains while engaging in various activities. As a major factor affecting railway passengers’ comfort, we investigated the effects lighting. Korean train cars required to have two rows light-emitting diode lights with minimum illuminance 500 lx, so examined changes cerebral blood flow under conditions around this threshold value. We used functional near-infrared spectroscopy measure prefrontal cortex activation 29 college students values 300, 500, 800 lx color-temperature 2700 K (bulb color), 4000 (white 5500 (blue color). Mean brain activity were compared using analysis variance. Of 48 channels, significant interaction between color responses observed for channel 38, as well right dorsolateral among different regions Brodmann area (p < 0.05). Oxygenated hemoglobin concentrations had consistently negative all treatment combinations, individual analyses based single-sample Student’s t-tests showed degrees channels areas. Meanwhile, comparison absolute indicated that level was more comfortable than levels 300 white bulb blue color.

Research investigating the neural processes related to music perception and production constitutes a well-established field within cognitive neurosciences. While most neuroimaging tools have limitations in studying complexity of musical experiences, functional Near-Infrared Spectroscopy (fNIRS) represents promising, relatively new tool for both laboratory ecological settings, which is also suitable typical pathological populations across development. Here we systematically review fNIRS studies on cognition, highlighting prospects potentialities. We include an overview basic theory, together with brief comparison characteristics other tools. Fifty-nine meeting inclusion criteria (i.e., using as primary stimulus) are presented five thematic sections. Critical discussion methodology leads us propose guidelines good practices aiming robust signal analyses reproducibility. A continuously updated world map proposed, including information from criteria. It provides organized, accessible, updatable reference database, could serve catalyst future collaborations community. In conclusion, shows potential music, particularly contexts special populations, aligning current research priorities cognition.

Understanding the intricate functions of human brain requires multimodal approaches that integrate complementary neuroimaging techniques. This review systematically examines integration functional magnetic resonance imaging (fMRI) and near-infrared spectroscopy (fNIRs) in research, addressing their synergistic potential, methodological advancements, clinical neuroscientific applications, persistent challenges. We conducted a comprehensive literature 63 studies (from PubMed Web Science up to September 2024) using keyword combinations such as fMRI, fNIRs, imaging. Our analysis reveals three key findings: (1) Methodological Synergy: Combining fMRI's high spatial resolution with fNIRs's superior temporal portability enables robust spatiotemporal mapping neural activity, validated across motor, cognitive, tasks. Additionally, this study experimental paradigms data processing techniques essential for effective neuroimaging. (2) Applications: The categorizes methodologies into synchronous asynchronous detection modes, highlighting respective applications localization, validation efficacy, mechanism discovery. Synchronous modes have advanced research neurological disorders (e.g., stroke, Alzheimer's), social cognition, neuroplasticity, while novel hyperscanning extend naturalistic, interactive settings. (3) Challenges: Hardware incompatibilities electromagnetic interference MRI environments), limitations restricted motion paradigms), fusion complexities hinder widespread adoption. future direction emphasizes hardware innovation (such fNIR probe compatible MRI), standardized protocol driven by machine learning, etc. solve depth limitation infer subcortical activities. synthesis underscores transformative potential fMRI-fNIRs bridging gaps neuroimaging, enhancing diagnostic therapeutic strategies paving way innovations research.

Railways are considered an environmentally sustainable mode of transportation but can pose significant environmental challenges due to their operation and associated activities. Among these, noise generation is a persistent source public complaints. In Korea, maximum distance 100 m from buildings has been proposed for new railway developments in residential areas, although this guideline lacks solid foundation based on experimental evidence. Noise barriers often installed as mitigation measure; however, there no standardized height relation effectiveness at varying distances.
