Neurofeedback: New Territories And Neurocognitive Mechanisms Of Endogenous Neuromodulation, James Sulzer, T Dorina Papageorgiou, Rainer Goebel, Talma Hendler

Faculty, Staff and Students Publications

Neurofeedback (NF) is endogenous neuromodulation of circumscribed brain circuitry. While its use of real-time brain activity in a closed-loop system is similar to brain-computer interfaces, instead of controlling an external device like the latter, the goal of NF is to change a targeted brain function. In this special issue on NF, we present current and future methods for extracting and manipulating neural function, how these methods may reveal new insights about brain function, applications, and rarely discussed ethical considerations of guiding and interpreting the brain activity of others. Together, the articles in this issue outline the possibilities of NF use …

Myosin Xva Isoforms Participate In The Mechanotransduction-Dependent Remodeling Of The Actin Cytoskeleton In Auditory Stereocilia, Ana I. López-Porras, Ava M. Kruse, Mark T. Mcclendon, A. Catalina Vélez-Ortega

Neurology Faculty Publications

Auditory hair cells form precise and sensitive staircase-like actin protrusions known as stereocilia. These specialized microvilli detect deflections induced by sound through the activation of mechano-electrical transduction (MET) channels located at their tips. At rest, a small MET channel current results in a constant calcium influx which regulates the morphology of the actin cytoskeleton in the shorter ‘transducing’ stereocilia. However, the molecular mechanisms involved in this novel type of activity-driven plasticity in the stereocilium cytoskeleton are currently unknown. Here, we tested the contribution of myosin XVA (MYO15A) isoforms, given their known roles in the regulation of stereocilia dimensions during hair …

Fall 2024 OTD Capstone Symposium

The standard of care for those with ALS includes range of motion, limb relaxation, trunk balance, and gait training (Braga et al., 2018). This study examines perceived quality of life in ALS clients before and after an in-person exercise program and home exercise program to evaluate the benefits of exercise as exercise does not exacerbate symptoms of ALS (Meng et al., 2020). Daily occupation performance requires functional ability which may be preserved through exercise (Kalron et al., 2021).

Blood Biomarkers In Down Syndrome: Facilitating Alzheimer's Disease Detection And Monitoring, Melissa Petersen, Lisi Flores-Aguilar, Elizabeth Head, Laia Montoliu-Gaya, Andre Strydom, Sarah Pape, Juan Fortea, Nicholas Ashton, Chinedu Momoh, Sid O'Bryant

Brain and Mind Institute

Blood-based biomarkers continue to be explored for disease detection, monitoring of progression, and therapeutic outcomes as the diagnostic determination of Alzheimer's Disease in Down Syndrome (DS-AD) remains challenging in clinical settings. This perspective highlights the current status of this effort. Overall, amyloid (A), tau (T), and neurodegeneration (AT[N]) blood-based biomarkers have been shown to increase with disease pathology for individuals with DS. Phosphorylated tau biomarkers (p-tau217, p-tau181) have been consistently shown to track disease progression for DS-AD and are likely good candidates for use in clinical settings. Biomarkers of inflammation (glial fibrillary acidic protein) also show promise; however, additional work …

Synthesis Of Photocleavable Molecules For Neurological Applications, Nishal Madujith Egodawaththa Arachchilage Don

Theses and Dissertations

In recent biomedical research, the precise control of molecular dynamics through light activation has emerged as a powerful tool, particularly in the field of neurobiology. This approach involves the use of photocleavable cages or photoprotective groups (PPGs) that are chemically tethered to biologically active molecules such as neurotransmitters or calcium chelators. These cages remain inert until exposed to specific wavelengths of light, typically in the visible range, triggering the release of the active compound with high spatiotemporal precision.

For neurotransmitter systems, such as glutamate (Glu), which plays a critical role in synaptic transmission and memory formation, researchers have developed novel …
