Brief Summary:

Background:

- 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.

Detailed Description:

Objective: to cross-validate our near infrared spectroscopy (NIRS) imaging system with existing functional magnetic resonance imaging (fMRI) and electroencephalogram (EEG) data, and b) to investigate any significant technical issues associated with optode placement and motion artifacts, and to explore techniques that will potentially improve the feasibility and reliability of the system according to the needs of the population whom existing imaging systems are unsuitable.

Study population: 250 healthy volunteers

Design: The study will look for correlations between NIRS signal changes in healthy subjects when performing functional tasks, and existing fMRI data.

Outcome Measures: graded changes in blood flow and oxygen, measured with NIRS, in response to different functional tasks.

Primary Outcome Measures :
  1. Collect functional optical imaging data [ Time Frame: End of study ]
    Collect functional optical imaging data from healthy volunteers, study patterns of near-surface cortical activation during performance of known tasks, and validate results with published literature

  2. Validate NIRFI imaging data results with fMRI data [ Time Frame: End of study ]
    Validate NIRFI imaging data results with fMRI data and assess the uses of NIRS techniques as developing neuroimaging modality


Secondary Outcome Measures :
  1. Assess any significant issues associated with NIRS optode placement [ Time Frame: End of study ]
    Assess any significant issues associated with NIRS optode placement and evaluate the effect of subject motion on data collection, quality, and noise

  2. Assess neurovascular changes [ Time Frame: End of study ]
    Assess neurovascular changes, including blood volume and blood oxygenation fluctuations, during functional events and validate observed changes with published literature
