People with Parkinson's disease (PD) may have difficulty stopping or changing their movements, especially when walking around obstacles. The goal of this observational study is to learn if a specific cognitive function, called inhibitory control (the ability to stop or control actions) is associated with gait adaptability in people with Parkinson's disease. Gait adaptability means the ability to adjust how a person walks in response to changes in the environment, such as stepping over obstacles. The main questions the study aims to answer are: * If brain activation related to inhibitory control, measured by EEG, is associated with gait adaptability during obstacle crossing in people with Parkinson's disease? * If behavioral inhibitory control is associated with gait adaptability during obstacle crossing in people with Parkinson's disease? Participants take part in one study visit. During this visit, participants complete simple thinking tests, have their brain activity recorded using EEG, and perform walking tasks that include stepping over obstacles.
