Evidence of cognitive activity in functional near infrared spectroscopy signal
نویسندگان
چکیده
We show that functional near infrared spectroscopy signals can monitor task-related cerebral hemodynamic response. We detect periodicities in the near infared spectroscopy signals and show that the estimated periods are consistent across multiple detectors and subjects, despite the jittered periodicity of the stimuli sequence that is used in a target categorization experiment. ©2003 American Society of America OCIS codes: (170.3880 Medical and biological imaging; (170.5280) Photon migration

Optical Imaging of the Motor Cortex in the Brain in Order to Determine the Direction of the Hand Movements Using Functional Near-Infrared Spectroscopy (fNIRS)
Introduction: In recent years, optical imaging has attracted a lot of attention from scholars as a non- aggressive, efficient method for evaluating the activities of the motor cortex in the brain. Functional near-infrared spectroscopy (fNIRS (is a tool showing the hemodynamic changes in a cortical area of the brain according to optical principles. The present study has been de...

We propose using functional near-infrared spectroscopy (fNIRS) to measure brain activity during driving tasks. Functional NIRS is a relatively new brain sensing technology that is portable and noninvasive, making it possible to sense brain activity in environments that would not be possible using most traditional imaging techniques. This provides us with the opportunity to better understand cha...

متن کاملNeurophotonics: non-invasive optical techniques for monitoring brain functions.
The aim of this review is to present the state of the art of neurophotonics, a recently founded discipline lying at the interface between optics and neuroscience. While neurophotonics also includes invasive techniques for animal studies, in this review we focus only on the non-invasive methods that use near infrared light to probe functional activity in the brain, namely the fast optical signal...
متن کاملStudying Neonates’ Language and Memory Capacities with Functional Near-Infrared Spectroscopy
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 capacities using functional near-infrared spectroscopy (fNIRS): the block design and the familiarization-recognition design. We review some of...
