Caffeine Effect on Cognitive Function during a Stroop Task: fNIRS Study
Neural Plasticity, 2020 Acting as a brain stimulant, coffee resulted in heightening alertness, keeping arousal, improving executive speed, maintaining vigilance, and promoting memory, which are associated with attention, mood, and cognitive function.

Informatics in Medicine Unlocked, 2020 Background: Functional Near-Infrared Spectroscopy (fNIRS) is a non-invasive technique for studying brain hemodynamics. Since brain hemodynamics also involves components from the heart rate (HR), it is possible to extract the HR signal from the fNIRS (EHR)

Studying Neonates’ Language and Memory Capacities with Functional Near-Infrared Spectroscopy [PDF]
, 2011 The measurement of newborns’ brain hemodynamic activity has improved our understanding of early cognitive processes, in particular of language acquisition. In this paper, we describe two experimental protocols adapted to study neonates’ speech processing

Frontiers in Human Neuroscience, 2018 The mirror neuron system (MNS), mainly including the premotor cortex (PMC), inferior frontal gyrus (IFG), superior parietal lobule (SPL), and rostral inferior parietal lobule (IPL), has attracted extensive attention as a possible neural mechanism of ...

Advanced Engineering Informatics, 2020 Shutdown maintenance, i.e., turning off a facility for a short period for renewal or replacement operations is a highly stressful task. With the limited time and complex operation procedures, human stress is a leading risk.

Uncovering the impact of the cardiovascular system on cerebrovascular health using MRI
Experimental Physiology, EarlyView.Abstract Human cerebrovasculature is finely tuned to enable local changes in blood flow to meet the brain's demands, whilst protecting the brain from systemic changes in blood pressure, both acutely during a heartbeat and chronically over time. This review summarises cerebrovascular structure and function, their role in disease and neurodegeneration ...

A functional near infrared spectroscopy (fNIRS) replication of the sunscreen persuasion paradigm
Social Cognitive and Affective Neuroscience, 2018 Activity in medial prefrontal cortex (mPFC) during persuasive messages predicts future message-consistent behavior change, but there are significant limitations to the types of persuasion processes that can be invoked inside an MRI scanner. For instance, real world persuasion often involves multiple people in conversation.

Acute exercise‐induced improvements in cognition: Role of cerebral blood flow and metabolism
Experimental Physiology, EarlyView.Abstract Physical activity is widely recognized for its ability to promote brain health, with acute exercise transiently enhancing cognition and long‐term training attenuating cognitive decline. However, the mechanisms underlying these benefits remain incompletely understood.

Developmental Cognitive Neuroscience, 2018 Both social perception and temperament in young infants have been related to social functioning later in life. Previous functional Near-Infrared Spectroscopy (fNIRS) data (Lloyd-Fox et al., 2009) showed larger blood-oxygenation changes for social ...

Experimental Physiology, EarlyView.Abstract Cerebral blood flow (CBF) is essential for sustaining neuronal metabolism and cognitive performance; however, the precise relationship between perfusion and cognition remains unclear. Although ageing and disease are associated with progressive declines in CBF and cognitive impairment, the acute effects of altered CBF under environmental ...
