Enhanced beta-band activity recorded in patients suffering from Parkinson's Disease (PD) has been described as a potential physiomarker for disease severity. Beta power is suppressed by Levodopa intake and STN deep brain stimulation (DBS) and correlates with disease severity across patients. The aim of the present study was to explore the promising signature of the physiomarker in the spatial domain.

The aim of this study was to investigate the potential association between oscillatory activity in the STN and symptom severity in PD.
Methods: Subthalamic local field potentials were recorded from 63 PD patients in a dopaminergic OFF state.
Article Synopsis
- The study aimed to compare the accuracy of measuring cortical bone thickness using low- and high-frequency ultrasound (US) against cone-beam computed tomography (CBCT) and stereomicroscopy.
- Ten jawbone models made from bovine ribs and porcine gingiva were evaluated, with implants inserted and measurements taken using all three methods.
- Ultrasound measurements were found to be quite accurate, especially directly above the implant, suggesting it could be a valuable supplement to CBCT for assessing bone thickness.
