Validation of a Novel Cerebellar-striatal Satiety Circuit in Humans
Brigham and Women's Hospital
150 participants
Dec 5, 2024
INTERVENTIONAL
Conditions
Summary
This study uses a noninvasive technique called transcranial magnetic stimulation (TMS) to study satiety in healthy individuals. TMS is a noninvasive way of stimulating the brain, using a magnetic field to change activity in the brain. The magnetic field is produced by a coil that is held next to the scalp. In this study, the investigators will be stimulating the brain to learn more about the role of the cerebellum in satiety.

Interventions
rTMS is a technique of TMS that allows for selective external manipulation of neural activity in a non-invasive manner. During rTMS a rapidly changing current is passed through an insulated coil placed against the scalp. This generates a temporary magnetic field, which in turn induces electrical current in neurons and allows for modulation of neural circuitry. Intermittent theta burst stimulation (iTBS) consisting of 2 s trains of 3 pulses at 50 Hz, repeated at 5 Hz, every 10s for a total of 600 pulses (82), will be applied to the target. Cerebellar stimulation will be applied to the targets at 100% of aMT or 35% maximal stimulator output, whichever is higher.

Sham is achieved by using a coil with a magnetic shield preventing magnetic field from reaching the head.
