Auditory Cues Modulate the Short Timescale Dynamics of STN Activity During Stepping in Parkinson’s Disease

Patients with Parkinson’s Disease (PD) often experience gait impairments, which severely affect their quality of life. Previous studies have suggested that β-frequency (15-30 Hz) oscillatory activity in the basal ganglia may be associated with gait impairments, but the exact dynamics of these oscillations during the gait process remain unclear. Add...

A Double-Hurdle Quantification Model for Freezing of Gait of Parkinson’s Patients

Research on Quantitative Model for Freezing of Gait in Parkinson’s Patients Background Introduction Parkinson’s Disease (PD) is a common neurodegenerative disease, accompanied by complex motor disorders. In the later stages of Parkinson’s disease, the phenomenon of “Freezing of Gait” (FOG) becomes particularly prominent. FOG refers to a transient p...

Quantification and Diagnosis of Mobility Deficits

Background and Research Motivation Parkinson’s Disease (PD) is a neurodegenerative disorder primarily affecting patients’ motor abilities, leading to tremors, bradykinesia, limb rigidity, and problems with gait and balance. These motor deficits significantly impact patients’ ability to live independently and their quality of life. Statistics predic...

Staged Bilateral MRI-Guided Focused Ultrasound Subthalamotomy for Parkinson Disease

MRI-Guided Staged Bilateral Focused Ultrasound Subthalamotomy for Parkinson’s Disease Background Parkinson’s Disease (PD) is a common neurodegenerative disorder, characterized mainly by motor symptoms such as tremor, rigidity, and bradykinesia. Traditionally, treatments for PD include medication and surgical interventions such as Deep Brain Stimula...

Dopamine and Serotonin in Human Substantia Nigra Track Social Context and Value Signals During Economic Exchange

Dopamine and Serotonin in Human Substantia Nigra Track Social Context and Value Signals During Economic Exchange

Background Introduction In contemporary neuroscience research, dopamine and serotonin are hypothesized to be crucial neuromodulators guiding social behavior. However, there is a significant lack of understanding regarding the dynamic changes of these neuromodulators during social interactions. Although non-invasive functional neuroimaging methods (...
