These experiments are conducted on an MRI scanner that is similar to an MRI scanner found in hospitals. MRI is very safe, as it does not use ionizing radiation (like x-rays) and is completely non-invasive.

Functional MRI is a particular type of MRI scan that allows researchers to obtain pictures of brain activity over time. While these images are being taken, subjects are asked to perform different cognitive "tasks" designed to evoke different kinds of mental activity. Typical tasks might include pressing different buttons according to the identity of a visually presented word or picture.

Participants are given pictures of their brains (similar to that shown below) and may be monetarily compensated or receive Experimetrix credit (GA Tech students only), depending upon the particular experiment.

Normal glasses can not be worn inside the MRI scanner. If you wear contact lenses, please remember to wear them the day of your appointment. However, if you do not have contacts or do not want to wear them, we will provide you with MRI-safe glasses that match your own prescription.

There is one final, very important point to be made regarding participation in these MRI experiments. The MRI scan being done is designed to answer research questions, not to medically examine your brain. The MRI scan is not a substitute for one a physician would order. It may not show problems that would be picked up by a medical MRI scan. None of the researchers are medically qualified radiologists. However, if we see something unusual in your scan, we will inform you so that you can obtain a follow-up evaluation by your physician. Any follow-up evaluation or treatment that you seek will be at your own expense.

If you have reason to think that you require an MRI scan for health reasons, please contact a physician.
