Mental workload classification using convolutional neural networks based on fNIRS-derived prefrontal activity

open access: yesBMC Neurology, 2023
Background Functional near-infrared spectroscopy (fNIRS) is a tool to assess brain activity during cognitive testing. Despite its usefulness, its feasibility in assessing mental workload remains unclear. This study was to investigate the potential use of

Emotional modulation of visual cortex activity: A functional nearinfrared spectroscopy study [PDF]

open access: yes, 2009
Functional neuroimaging and electroencephalography reveal emotional effects in early visual cortex. Here, we used fNIRS to examine haemodynamic responses evoked by neutral, positive and negative emotional pictures, matched for brightness, contrast, hue,

Measurement of Brain Function of Car Driver Using Functional Near‐Infrared Spectroscopy (fNIRS) [PDF]

open access: yesComputational Intelligence and Neuroscience, 2009
The aim of this study is to propose a method for analyzing measured signal obtained from functional Near‐Infrared Spectroscopy (fNIRS), which is applicable for neuroimaging studies for car drivers. We developed a signal processing method by multiresolution analysis (MRA) based on discrete wavelet transform.

Real-Time State Estimation in a Flight Simulator Using fNIRS [PDF]

open access: yes, 2015
Working memory is a key executive function for flying an aircraft. This function is particularly critical when pilots have to recall series of air traffic control instructions. However, working memory limitations may jeopardize flight safety.

Age-related changes in global motion coherence: conflicting haemodynamic and perceptual responses [PDF]

open access: yes, 2018
Our aim was to use both behavioural and neuroimaging data to identify indicators of perceptual decline in motion processing. We employed a global motion coherence task and functional Near Infrared Spectroscopy (fNIRS). Healthy adults (n = 72, 18-85) were
