Tokyo, June 1 -- UMIN Clinical Trials Registry (UMIN-CTR) received information related to the study (UMIN000061736) titled 'Effects of low-frequency weak electrical brain stimulation on motor skill improvement and brain activity' on June 1.

Study Type: Interventional

Study Design: Basic Design - Cross-over Randomization - Randomized Blinding - Single blind -investigator(s) and assessor(s) are blinded Control - Placebo

Primary Sponsor: Institute - Niigata university of health and welfare

Condition: Condition - Healthy adults Classification by malignancy - Others Genomic information - NO

Objective: Narrative objectives1 - The aim of this study is to clarify the effects of low-frequency transcranial alternating current stimulation (tACS) on finger dexterity and reaction performance. In addition, neural mechanisms underlying the effects of brain stimulation will be investigated by assessing changes in brain activity using functional magnetic resonance imaging (fMRI), electroencephalography (EEG), and transcranial magnetic stimulation (TMS). Basic objectives2 - Efficacy

Intervention: Interventions/Control_1 - M1-tACS group Interventions/Control_2 - Cerebellum-tACS group

Eligibility: Age-lower limit - 18 years-old = Gender - Male and Female Key inclusion criteria - Healthy adults, primarily undergraduate and graduate students at our university, who voluntarily expressed their willingness to participate after receiving an explanation of the study from the principal investigator. Key exclusion criteria - Individuals with neurological or psychiatric disorders Individuals with metal implants or electronic devices such as pacemakers in the body Individuals taking neuroactive medications Individuals with claustrophobia related to fMRI measurements Pregnant individuals Target Size - 80

Recruitment Status: Recruitment status - Preinitiation Date of protocol fixation - 2026 Year 06 Month 01 Day Anticipated trial start date - 2026 Year 07 Month 01 Day Last follow-up date - 2031 Year 03 Month 31 Day
