A Study of Retatrutide (LY3437943) in the Maintenance of Weight Reduction in Individuals With Obesity
Recruiting
This is a study of retatrutide in participants with obesity. The main purpose is to learn more about how retatrutide maintains body weight loss. The study will have two treatment phases: an 80 week lead-in phase in which all participants will take retatrutide dose 1 and a 36 week randomized, double-blinded phase in which participants will either take retatrutide dose 1, retatrutide dose 2, or switch to placebo. Participation in the study will last around 125 weeks.

Characterization of an Optically Pumped Magnetometer (OPM) Magnetoencephalography (MEG) Array
Recruiting
Background:
Brain activity produces magnetic fields. These fields can be measured outside the head. Existing technology, called MEG, measures these fields. Researchers are testing a new type of magnetic field sensor called OPM. They hope it can help pinpoint with very high accuracy where brain activity is generated.
Objective:
To develop and test a new type of sensor for measuring the magnetic fields produced by brain activity.
