For Participants

Welcome to the Ances Laboratory

Thank you for your interest in our research. Our lab uses state-of-the-art scientific tools and methods to explore how the brain functions. We are also very interested in understanding how the brain changes with normal aging and neurodegenerative diseases. We are interested in seeing how these changes impact cognition. Furthermore, we are attempting to use this information to test novel therapies that could improve memory and attention deficits associated with normal aging and neurodegenerative disorders (including Alzheimer’s Disease, HIV Associated Neurocognitive Disorder, and Crutezfeld-Jacob Disease).

Are you eligible to be a research participant?
We are always interested in recruiting individuals who are willing to be research participants. If you are between the ages of 18 and 90 years of age and would be interested in participating in one of our studies, please continue to read about our research and contact us for a more detailed explanation.

Studies by tool:
Our lab uses several different research tools to study cognition in both healthy individuals as well as participants with neurodegenerative disorders. What all of our studies have in common is that you will be some cognitive experiments that require you to do some pencil and paper tests and possibly play some video games. What follows is a description of the types of studies you may be appropriate to participate in:

  • Behavioral studies. Some of our experiments are purely behavioral. This means that you sit and do simple pen and paper tasks or watch images on a computer screen and respond to different tasks by pressing a button.
  • fMRI studies. In some of our experiments, we record your brain activity using an MRI scanner. Functional MRI allows us to see both the structure of your brain and brain activity. The MRI scan for this study takes approximately 1 hour to complete. Each subject lies on the scanner bed with a pillow and warm blanket for comfort. The subject will wear headphones and be able to listen to music during the scan. The headphones are also useful to cancel the noise of the scanner itself, which will make clicking noises throughout the scan. The subject will be asked to remove all metal, including identification and credit cards, from his/her person before having the scan done (there are lockers available to store these items). Subjects are asked to keep their heads as still as possible because movement will blur the images that are taken. If you would like more information on the MRI machine or where the MRIs will be performed please visit the Center for Clinical Imaging Research (CCIR) visit their web site!

All participants are compensated for the time that they commit to our studies. If you are interested in participating with us, please call us at (314) 362-9731 with your name, phone number, and best time to reach you. We will contact you as soon as we can. All information is kept confidential.
