- Non-invasive functional near infrared (fNIR) imaging techniques use infrared light to detect changes in blood volume and oxygen levels during brain activity. fNIR is being studied as a possible way to examine the brain activity of individuals who are unable to undergo standard brain function imaging techniques (such as functional magnetic resonance imaging, or fMRI). For instance, war veterans who have iron shrapnel in the body are not able to have fMRI scans, and very young children or children with autism and related disorders are often not able or willing to cooperate long enough in the MRI environment to allow full imaging studies to take place. Researchers are interested in comparing the results of fNIR and fMRI performed on healthy volunteers to determine if fNIR produces similarly accurate results.
Objectives:
- To examine the capabilities of non-invasive functional near infrared imaging techniques on healthy volunteers and compare the results with the existing outcomes of functional magnetic resonance imaging.
Eligibility:
- Healthy volunteers at least 18 years of age.
Design:
- Participants will have one study visit. Depending on the complexity of the task, the whole exam will take between 5 minutes and 1 hour to perform.
- Participants will be asked to sit as still as possible while wearing a headband that includes light sources and detectors (the fNIR device).
- Participants will be asked to perform a set of tasks (e.g., reading sentences or counting numbers in one s head). Data will be collected during these experiments.
