Using multivariate partial least squares on fNIRS data to examine load-dependent brain-behaviour relationships in aging

Researchers implementing non-invasive neuroimaging have reported distinct load-dependent brain activity patterns in older adults compared with younger adults. Although findings are mixed, these age-related patterns are often associated with …

Association of Compensatory Mechanisms in Prefrontal Cortex and Impaired Anatomical Correlates in Semantic Verbal Fluency: A Functional Near-Infrared Spectroscopy Study

Objective Semantic verbal fluency (SVF) engages cognitive functions such as executive function, mental flexibility, and semantic memory. Left frontal and temporal lobes, particularly the left inferior frontal gyrus (IFG), are crucial for SVF. This …

Freezing of gait in Parkinson's disease is related to imbalanced stopping–related cortical activity

Freezing of gait, characterized by involuntary interruptions of walking, is a debilitating motor symptom of Parkinson's disease that restricts people's autonomy. Previous brain imaging studies investigating the mechanisms underlying freezing were …

Investigating the Neural Correlates of Different Levels of Situation Awareness and Work Experience

Maintaining good situation awareness is crucial for workers’ safety on the dynamic and complex construction site, and workers with more experience may contribute to better performance in safety. However, little research has investigated the cognitive …

Brainstorming: Interbrain coupling in groups forms the basis of group creativity

Although the impact of group dynamics on creativity is widely recognized, prior research has primarily concentrated on individuals in isolation from social context. To address this lacuna, we focus on groups as the fundamental unit of analysis. We …

Flexible circuit-based spatially aware modular optical brain imaging system for high-density measurements in natural settings

Significance Functional near-infrared spectroscopy (fNIRS) presents an opportunity to study human brains in everyday activities and environments. However, achieving robust measurements under such dynamic conditions remains a significant challenge. …

Prenatal affective cognitive training to reduce the risk of postpartum depression (PACT): study protocol for a randomized controlled trial

Background: Postpartum depression (PPD) affects 30–50% of women with a history of previous depression or bipolar disorder and 8% of women with no history of depression. Negative cognitive biases in the perception of infant cues and difficulties with …

Altered functional connectivity subserving expressed emotion environments in schizophrenia: An fNIRS study

Living in high-expressed emotion (EE) environments, characterized by critical, hostile, or over-involved family attitudes, has been linked to increased relapse rates among individuals with schizophrenia (SZ). In our previous work (Wang et al., 2023), …

The physiologic complexity of prefrontal oxygenation dynamics is associated with age and executive function: an exploratory study

Background: The hemodynamics of prefrontal cortex (PFC) oxygenation are regulated by numerous processes operating over multiple temporal scales, producing complex patterns in its output fluctuations. Age may alter this multiscale regulation of PFC …
