The effect of transcranial magnetic stimulation using intermittent theta burst stimulation (iTBS) on functional connectivity and cortical excitability was tested in a healthy older adult and individuals with mild cognitive impairment. Individuals underwent an iTBS protocol with single pulse cortical excitability tests and-resting state fMRI(rs-fMRI) being performed before and after. Cortical excitability was tested through a pseudorandomized order of intensities of single pulses. Within functional network RS-fMRI analysis was done of the sensorimotor network. Differences in the response between the two populations was observed in both the functional connectivity changes in the sensorimotor network as well as the cortical excitability.
