Summary

The purpose of this study is to investigate the immediate effects of non-invasive temporal interference stimulation (TIS) targeting the striatum on sentence processing and brain connectivity in patients with neurodegenerative diseases.

Detailed description

The study aims to investigate the immediate effects of non-invasive temporal interference stimulation (TIS) targeting the deep structures of the fronto-striatal circuit involved in language processing. The research focuses on patients with neurodegenerative diseases who often suffer from communication deficits and impaired sentence comprehension. Participants will undergo a cross-over design consisting of a single session of active TIS directed at the striatum and a session of placebo stimulation. The stimulation will be administered in a randomized order. The duration of the stimulation is approximately 20 minutes. During the stimulation, participants will perform a sentence comprehension task. Resting-state fMRI measurements will be taken before and after the stimulation to evaluate offline effects on brain connectivity and potential neuroplasticity.
