The goal of this preclinical study is to assess the effects of focused ultrasound stimulation to the cerebellum on brain dynamics and cognition in healthy volunteers aged 18 to 40. The main questions it aims to answer are:
Does FUS applied to the cerebellum affect cognition?
Does FUS applied to the white matter or gray matter of the cerebellum with the same parameters result in different outcomes?
Researchers will compare active and sham stimulations.
Participants will be asked to complete cognitive tasks after receiving FUS to the cerebellum.
