Examining Lateralized Aspects of Motor Control Using Non-invasive Neural Stimulation

Motor adaptation and generalization are believed to occur via the integration of various forms of sensory feedback for a congruent representation of the body's position in space along with estimation of inertial properties of the limb segments for accurate specification of movement. Thus, motor adaptation is often studied within curated environments incorporating a "mis-match" between different sensory systems (i.e. a visual field shift via prism googles or a visuomotor rotation via virtual reality environment) and observing how motor plans change based on this mis-match. However, these adaptations are environment-specific and show little generalization outside of their restricted experimental setup. There remains a need for motor adaptation research that demonstrates motor learning that generalizes to other environments and movement types. This work could then inform physical and occupational therapy neurorehabilitation interventions targeted at addressing motor deficits.

Advantage of Cerebellar Transcranial Magnetic Stimulation in Alzheimer's Diseases （ACT-AD）

Alzheimer's Disease (AD) is the primary cause of dementia, with its prominent feature being cognitive decline. The cerebellum plays a crucial role in cognitive processing, making it a potential target for therapeutic intervention. This study will be conducted to evaluate the efficacy and safety of cerebellar Intermittent theta-burst stimulation (CRB-iTBS) in participants with mild Alzheimer's disease on the change from baseline in the Clinical Dementia Rating-Sum of Boxes (CDR-SB) at 3 months of treatment in the Core Study. This project aims to provide a valid treatment to improve the cognitive function and quality of life for those with Alzheimer's disease.

Imaging Speech in Neurotypical Adults and Individuals With Cerebellar Stroke

The goal of this research study is to learn how the brain areas that plan and control movement interact with the areas responsible for hearing and perceiving speech in healthy adults and people who have had cerebellar strokes. The main questions it aims to answer are: 1. What regions of the brain's sensory systems show changes in their activity related to speech? 2. To what extent do these regions help listeners detect and correct speech errors? 3. What is the role of the cerebellum (a part of the brain in the back of the head) in these activities? Participants will be asked to complete several experimental sessions involving behavioral speech and related tests and non-invasive brain imaging using electroencephalography (EEG) and functional magnetic resonance imaging (fMRI).

The Study on the Efficacy of tDCS Stimulation of the Cerebellum Combined With XingNaoJing Injection in Patients With Consciousness Disorders After Cranial Injury

The purpose of this study is to investigate the effect of tDCS stimulation of cerebellum combined with Xingnaojing on patients with disturbance of consciousness after craniocerebral injury, and to clarify the relationship between the following two points: (1) to clarify whether MMN, P300, fNIRS, BAEP, SEP can be used as objective indicators to distinguish VS from MCS. (2) To clarify the changes of consciousness level and brain function in DoC patients with craniocerebral injury treated with tDCS stimulation of cerebellum combined with Xingnaojing.

Effects of 3-Month Melatonin Treatment on Regional Cerebellar Structure and Blood Biomarkers in Alzheimer's Disease Spectrum

The goal of this clinical trial is to explore and verify the preventive effects of melatonin on the progression of Alzheimer's disease. The study aims to analyze the changes in blood biomarkers (phosphorylated tau, glial fibrillary acidic protein, neurofilament chain), various sleep-related subjective report questionnaire scores, physical performance, cognitive function scores and cerebellar volume change after three months of melatonin administration in patients with Alzheimer's-type mild cognitive impairment (MCI) accompanied by insomnia. The main questions it aims to answer are: 1. Does melatonin administration alter the levels of blood biomarkers associated with Alzheimer's disease? 2. What changes occur in sleep-related subjective report questionnaire scores and cognitive function scores following melatonin administration? 3. Does melatonin administration effect on physical performance? 4. Is there any relations between cognitive decline, phsycal performance and cerebellar volume change? We will compare the data collected before and after melatonin administration to determine its preventive effects on Alzheimer's disease progression. Participants Will: 1. Take melatonin every day for 3 months and Complete sleep-related subjective report questionnaires, neuropsychological assessments and physical performance test 2. Visit the clinic at the initial visit and after 3 months for checkups and tests. 3. Complete sleep-related subjective report questionnaires and neuropsychological assessments and physical performance test 4. Provide blood samples for biomarker analysis.
