Time-gated photon counting in both confocal and offset configurations for cost-effective enhancement of functional near-infrared spectroscopy

APL Photonics
Time-of-flight functional near-infrared spectroscopy (fNIRS) is a promising technology for non-invasive functional neuroimaging due to the capability to monitor absolute blood oxygen information.

Fusion of fNIRS and fMRI data: Identifying when and where hemodynamic signals are changing in human brains

Frontiers in Human Neuroscience, 2013
In this study we implemented a new imaging method to fuse functional near infrared spectroscopy (fNIRS) measurements and functional magnetic resonance imaging (fMRI) data to reveal the spatiotemporal dynamics of the hemodynamic responses with high ...

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.

Quality analysis of heart rate derived from functional near-infrared spectroscopy in stress assessment

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)

Understanding Family Dynamics Through a Neurocognitive Lens

Journal of Family Theory &Review, EarlyView.
ABSTRACT Individual family members impact each other and the family system at the physiological, brain, behavioral, phenomenological, and social level. Previous research used established methods, such as self‐report and behavioral observation, to provide thorough insights into family dynamics.

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.

Unfolding the real-time neural mechanisms in addiction: Functional near-infrared spectroscopy (fNIRS) as a resourceful tool for research and clinical practice

Addiction Neuroscience, 2022
Neural underpinnings of addiction have been widely investigated using traditional neuroimaging techniques and paradigms. However, certain mechanisms are still underexplored, and existing studies often do not adopt an ecological assessment.

From Finger Taps to Footsteps: Gait as a Model for Investigating and Training Rhythmic Abilities

Annals of the New York Academy of Sciences, EarlyView.
Motor rhythmic abilities, like auditory–motor synchronization, are often assessed using finger‐tapping tasks. Here, we propose gait as a richer, more ecologically valid alternative, which engages the whole body, is continuous, and taps into both automatic and voluntary control.

Negative affect is related to reduced differential neural responses to social and non-social stimuli in 5-to-8-month-old infants: A functional near-infrared spectroscopy-study

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 ...
