Measuring Attention Span With Functional Mri

For a comprehensive assessment of attention, we collected original behavioural and functional magnetic resonance imaging (fMRI) data from more than 90 participants performing three...

Functional magnetic resonance imaging (fMRI) and electroencephalography (EEG) are two noninvasive methods commonly used to study neural mechanisms supporting visual attention in humans.

Here we provide a high-level review of current controversies and challenges in this growing subfield of neuroscience, highlighting examples where task fMRI data and rs-fMRI dataeither in isolation or combinedhave yielded significant insights into brain-behavior associations.

Given its fluctuations and multi-faceted nature, an individuals attentional functioning cannot be boiled down to a single number, so researchers have sought a quantifiable, standardized measure of attention.

Resting-state fMRI (rsfMRI) is a widely used neuroimaging technique that measures spontaneous fluctuations in brain activity in the absence of specific external cognitive, motor, emotional, and sensory tasks or stimuli, based on the blood-oxygen-level-dependent (BOLD) signal.

Functional magnetic resonance imaging (fMRI) blood oxygen level-dependent (BOLD) responses to stimuli of varying contrast.

Functional near-infrared spectroscopic imaging was employed to measure the concentration of brain oxyhaemoglobin in the subjects, while they were performing these four attention tasks.

Functional Magnetic Resonance Imaging (fMRI) is a class of imaging methods developed in order to demonstrate regional, time-varying changes in brain metabolism3,37,49.

This study used real-time functional magnetic resonance imaging (fMRI) for online decoding of attention to objects belonging to two.
