Individualized Closed Loop Transcranial Magnetic Stimulation (TMS) for Working Memory Enhancement
In Brief
A clinical study evaluating Functional Magnetic Resonance Imaging (fMRI) and Repetitive Transcranial Magnetic Stimulation (rTMS) for Memory. Completed, enrolled 27 participants across 1 site.
Detailed Summary
The study is investigating working memory brain states by using transcranial magnetic stimulation (TMS) in combination with functional magnetic resonance imaging (fMRI). The study uses a novel, individualized targeting approach for TMS based on each subject's individual multi-modal fMRI data. The individualized target will be stimulated in a TMS/ fMRI imaging session to investigate working memory states and optimal stimulation frequencies.
Study Details
Timeline
Interventions
Participants undergo resting-state and task-based fMRI to identify individualized transcranial magnetic stimulation (TMS) targets and determine optimal and sub-optimal stimulation frequencies. Additional fMRI scans are performed after each neuromodulation phase to assess changes following three days of stimulation at the optimal and sub-optimal frequencies.
Participants first receive multiple rTMS frequencies during an fMRI scan to assess brain responses and determine individualized optimal and sub-optimal stimulation frequencies. They then complete two neuromodulation intervention periods, receiving rTMS at the identified optimal and sub-optimal frequencies. Each frequency is administered over three consecutive days, with the order of conditions randomized and counterbalanced.
