How the Motor Cortex Plays a Role in Parkinson’s Disease

Ayesha Azeem ’23 Parkinson’s Disease is a brain disorder that leads to shaking, stiffness, and difficulty with walking and balance. The symptoms gradually begin and get progressively worse over time. Although neuroscientists understand the role of neuron and dopamine loss in Parkison’s Disease, little is known about how dopaminergic modulation affects brain regions that are involved in the control of voluntary movement. In the primary … Continue reading How the Motor Cortex Plays a Role in Parkinson’s Disease

Anatomical Etiology of AR Subtype of Parkinson’s Disease Linked to Altered Functional Connectivity

Vignesh Subramanian ’24 Parkinson’s disease (PD) is a neurodegenerative movement disorder causing progressive loss of motor control that afflicts over ten million people worldwide. The disease is characterized by a loss of dopaminergic neurons in the substantia nigra region of the brain, contributing to widespread network alterations that disrupt communication with the body’s muscles. PD patients are classified by their most prominent resulting clinical symptoms, … Continue reading Anatomical Etiology of AR Subtype of Parkinson’s Disease Linked to Altered Functional Connectivity

Music to One’s Ears: Familiarity and Music Engagement in People With Parkinson’s Disease

Thumyat Noe ’23 Parkinson’s disease is a brain disorder characterized by loss of dopamine and reduced innervation of neural structures that are responsible for coordination of motor movements. Affected individuals often have difficulty walking and maintaining balance. However, music has been shown to be a helpful external cue that reduces these symptoms. Research shows that exposure to music activates brain regions that are closely related … Continue reading Music to One’s Ears: Familiarity and Music Engagement in People With Parkinson’s Disease
