Summary

This trial uses a brain stimulation technique to help people with insomnia fall asleep. It targets a brain area involved in daydreaming and internal thoughts, reducing its activity before bedtime. The study aims to see if this method can improve sleep without using drugs. The procedure is non-invasive and has been studied for its potential in treating various sleep disorders.

Experimental Treatment

Group I: Sham cTBS first, then active cTBSExperimental Treatment2 Interventions

Participants complete an Enrollment Visit followed by one week of at-home actigraphy. Participants return to the lab for Overnight Visit 1 and undergo a MRI scan followed by sham cTBS and then another MRI scan followed by a night of polysomnographic monitored in-lab sleep. Participants return home and complete another week of at-home actigraphy. Participants then return to the lab for Overnight Visit 2 where they undergo a MRI scan followed by active cTBS and then another MRI scan followed by a night of polysomnographic monitored in-lab sleep.
