What are key reasons you might choose not to volunteer for this study?
fNIRS employs non-ionizing near-infrared light, so no cancerogeneous or genetic effects are possible. The light intensity is kept well below safety limits to avoid the risk of thermal damages. No cumulative harmful effects are known so that measurements can be applied repeatedly or in a continuous manner for monitoring purposes. The principal absorber in the near-infrared region in tissue is the pigment hemoglobin, which due to its confinement in the red cells, is highly concentrated in blood and therefore provides a strong optical contrast. This allows the sensitive imaging of local blood supply without additional contrast agents. fNIRS has been used with infants and very young children for many years because it is non-invasive and safe. The main inconvenience to you may be the time or travel commitment to visit our fNIRS lab. The main inconvenience to your child is that they may experience some discomfort from wearing the head cap that holds the light emitters and detectors against the head. If your child becomes fussy or too tired to participate, we can reschedule you for a second visit. For a complete description of risks, refer to the Informed Consent.
The alternative to participating in this study is to not volunteer for the study or to withdraw from the study. For a complete description of alternatives to participating, refer to the Informed Consent.
