Cranial Nerve Stimulation Study

The Monell Chemical Senses Center is looking for volunteers for a smell study to be conducted at the Center. This research explores the role of cranial nerve stimulation and how it impacts your sense of smell.

Eligible to adults 18 – 50 years of age. Subjects will be asked to detect, identify, discriminate, and evaluate various smells. Subjects may be asked to wear a small ear clip that contains an electrode that delivers a mild electrical impulse to stimulate cranial nerves.

The total estimated time of your participation in this study is up to 3 (three) hours over separate visits.

We will compensate subjects for participation and travel costs for each study visit. Compensation based upon completion of tasks and length of participation.

Some exclusion criteria apply; please contact the lab for more information.

Taste Perception Across the Globe

The Reed Lab is currently conducting a study to investigate global diversity in the perception of taste of certain medications. Many medication formulations are created, tested on, and based on information from mostly people of European descent. However, we know that perception of taste varies greatly and is likely to vary among different ethnic groups. Medicines that were created on a Eurocentric basis may taste entirely different to those of other ethnicities. Higher levels of medication bitterness can reduce medicine compliance for chronic, life-threatening ailments such as HIV-AIDs, parasite infections, and malaria. We are interested in this variability of taste, and how it may affect individuals’ taste of particularly bitter medicines. We are hoping to find people who represent diverse ancestral groups to participate in our research.

If you are interested or have any questions, please email lab manager Katie Bell at kbell@monell.org. Participants will be mailed a taste kit containing 12 solutions, which they will taste, make a rating on, and spit out. This will occur during a scheduled 30–45-minute Zoom meeting. A saliva sample must also be provided by subjects for DNA testing. Participants will be compensated for their time with a $50 Amazon gift card. The entire process is remote, in the comfort of your own home!

Healthy female volunteers needed to smell odor-filled pens 6 times a week for 6 weeks

Healthy females between the ages of 50 – 65 may qualify for a research study looking at the effect of odor training on olfactory performance. This study involves 2 visits to the Monell Center which will involve smelling odors and making ratings about those odors for the purpose of testing sensitivity and (on first session) instruction on the at-home sessions. These visits are separated by 6 weeks of at-home sessions, 6 sessions per week, each lasting ~10 minutes, with half of the sessions occurring under the supervision of an experimenter using video-conferencing technology.

You will receive $300 following the completion of the study. If you would like to participate in this study or have any questions, please send an email to daltonlab@monell.org.
