Digital Music Device (MedRhythms, Inc., Portland, ME)The purpose of this research study is to examine the effects of a 3-month personalized community-based walking program called MyMusiQ. The study uses music cues delivered through a digital device in people with Parkinson disease (PD). The investigators want to know if personalized music cueing through the digital device can improve walking quality, walking ability, daily walking amount and intensity, and quality of life, while helping walking feel more automatic and require less mental effort. Participants will take part in this research study for approximately 18 weeks in total. During this time, participants will complete 4 study visits at designated research centers at Boston University, Washington University in St. Louis, or the University of Utah, depending on the site of enrollment.

MR-005 (MedRhythms, Inc., Portland, ME)The purpose of this research study is to examine the effects of a 3-month personalized community-based walking program using a digital music-based device designed for self-directed gait training in people with Parkinson disease (PD). The study uses music cues delivered through this digital device to improve walking outcomes. The investigators want to know if personalized music cueing through the digital device can improve walking quality, walking ability, daily walking amount and intensity, and quality of life, while helping walking feel more automatic and require less mental effort.

Neural Mechanisms of Spatial Representations Beyond the SelfSpatial navigation is a fundamental human behavior, and deficits in navigational functions are among the hallmark symptoms of severe neurological disorders such as Alzheimer's disease. Understanding how the human brain processes and encodes spatial information is thus of critical importance for the development of therapies for affected patients. Previous studies have shown that the brain forms neural representations of spatial information, via spatially-tuned activity of single neurons (e.g., place cells, grid cells, or head direction cells), and by the coordinated oscillatory activity of cell populations. The vast majority of these studies have focused on the encoding of self-related spatial information, such as one's own location, orientation, and movements. However, everyday tasks in social settings require the encoding of spatial information not only for oneself, but also for other people in the environment. At present, it is largely unknown how the human brain accomplishes this important function, and how aspects of human cognition may affect these spatial encoding mechanisms. This project therefore aims to elucidate the neural mechanisms that underlie the encoding of spatial information and awareness of others. Specifically, the proposed research plan will determine how human deep brain oscillations and single-neuron activity allow us to keep track of other individuals as they move through our environment. Next, the project will determine whether these spatial encoding mechanisms are specific to the encoding of another person, or whether they can be used more flexibly to support the encoding of moving inanimate objects and even more abstract cognitive functions such as imagined navigation. Finally, the project will determine how spatial information is encoded in more complex real-world scenarios, when multiple information sources (e.g., multiple people) are present. To address these questions, intracranial medial temporal lobe activity will be recorded from two rare participant groups: (1) Participants with permanently implanted depth electrodes for the treatment of focal epilepsy through responsive neurostimulation (RNS), who provide a unique opportunity to record deep brain oscillations during free movement and naturalistic behavior; and (2) hospitalized epilepsy patients with temporarily implanted intracranial electrodes in the epilepsy monitoring unit (EMU), from whom joint oscillatory and single-neuron activity can be recorded.

Use of a Mobile Brain-Body Imaging Approach to Evaluate the Effects of Rhythmic Auditory Stimulation on Gait and Brain Function in Alzheimer's DiseaseAlzheimer's Disease (AD) is associated with impairments in both gait and cognition, significantly increasing fall risk. Falls are a leading cause of injury-related disability in older adults, and individuals with AD experience a nearly threefold higher rate of falls compared to neurotypical older adults. There is an urgent need for fall prevention interventions tailored to the unique deficits of individuals with AD. Converging evidence suggests that interventions aiming to reduce fall risk in AD should target both gait and cognition. Rhythmic music interventions, such as Rhythmic Auditory Stimulation (RAS) can harness global brain activation and auditory-motor entrainment to facilitate high-intensity exercise to alleviate AD-related neurocognitive and gait dysfunction. This study aims to assess the neural correlates of gait dysfunction in people with AD, evaluate if baseline neurocognitive impairment is predictive of the effects of RAS, and evaluate RAS benefits for individuals with AD.
