Prefrontal cortex involvement during dual-task stair climbing in healthy older adults: An fNIRS study

Executive function and motor control deficits adversely affect gait performance with age, but the neural correlates underlying this interaction during stair climbing remains unclear. Twenty older adults (72.7 ± 6.9 years) completed single tasks: …

Investigating the Utility of fNIRS to Assess Mental Workload in a Simulated Helicopter Environment

Functional near-infrared spectroscopy (fNIRS) has been used with moderate success in many passive brain-computer interface applications. Much of this recent work has been focused on differentiating between various states shortly following discrete …

A functional near-infrared spectroscopy (fNIRS) examination of how self-initiated sequential movements become automatic

The neural mechanisms underlying movement automaticity have been investigated using PET and fMRI and more recently functional near-infrared spectroscopy (fNIRS). As fNIRS is an emerging technique, the objective of the present study was to replicate …

Aging effects on prefrontal cortex oxygenation in a posture-cognition dual-task: an fNIRS pilot study

Background: The aging process alters upright posture and locomotion control from an automatically processed to a more cortically controlled one. The present study investigated a postural-cognitive dual-task paradigm in young and older adults using …

Temporal cortex activation to audiovisual speech in norma-hearing and cochlear implant users measured with functional near-infrared spectroscopy

Background: Speech understanding may rely not only on auditory, but also on visual information. Non-invasive functional neuroimaging techniques can expose the neural processes underlying the integration of multisensory processes required for speech …

Combined EEG-fNIRS decoding of motor attempt and imagery for brain switch control: An offline study in patients with tetraplegia

Combining electrophysiological and hemodynamic features is a novel approach for improving current performance of brain switches based on sensorimotor rhythms (SMR). This study was conducted with a dual purpose: to test the feasibility of using a …
