Scale invariance in fNIRS as a measurement of cognitive load [PDF]

Cortex, 2021
Abstract Scale invariant neural dynamics are a relatively new but effective means of measuring changes in brain states as a result of varied cognitive load and task difficulty. This study is the first to test whether scale invariance (as measured by the Hurst exponent, H ) can be ...

Functional near infrared spectroscopy (fNIRS) to assess cognitive function in infants in rural Africa [PDF]

, 2011
Cortical mapping of cognitive function during infancy is poorly understood in low-income countries due to the lack of transportable neuroimaging methods. We have successfully piloted functional near infrared spectroscopy (fNIRS) as a neuroimaging tool in

Sleep Is a Refreshing Process: An fNIRS Study [PDF]

Frontiers in Human Neuroscience, 2019
Sleep is a very critical process that constitutes up to one third of daytime of a healthy adult. It is known to be an active period where body and brain is refreshed for the next day. It is both part of a larger cycle, i.e., circadian rhythm, and has subcsycles in it, i.e., sleep stages.

Mocarts: a lightweight radiation transport simulator for easy handling of complex sensing geometries [PDF]

, 2016
In functional neuroimaging (fNIRS), elaborated sensing geometries pairing multiple light sources and detectors arranged over the tissue surface are needed. A variety of software tools for probing forward models of radiation transport in tissue exist, but

Brain oxygenation patterns during the execution of tool use demonstration, tool use pantomime, and body-part-as-object tool use [PDF]

, 2015
© 2015 Elsevier B.V. Divergent findings exist whether left and right hemispheric pre- and postcentral cortices contribute to the production of tool use related hand movements. In order to clarify the neural substrates of tool use demonstrations with tool
