Non-invasive, low intensity focused ultrasound is an emerging neuromodulation technique that offers the potential for precision, personalized therapy. An increasing body of research has identified mechanosensitive ion channels that can be modulated by FUS and support acute electrical activity in neurons. However, neuromodulatory effects that persist from hours to days have also been reported.

The Parkinson's Families Project is a UK-wide study aimed at identifying genetic variation associated with familial and early-onset Parkinson's disease (PD). We recruited individuals with a clinical diagnosis of PD and age at motor symptom onset ≤45 years and/or a family history of PD in up to third-degree relatives. Where possible, we also recruited affected and unaffected relatives.

The stochastic block model (SBM) and degree-corrected block model (DCBM) are network models often selected as the fundamental setting in which to analyze the theoretical properties of community detection methods. We consider the problem of spectral clustering of SBM and DCBM networks under a local form of edge differential privacy. Using a randomized response privacy mechanism called the edge-flip mechanism, we develop theoretical guarantees for differentially private community detection, demonstrating conditions under which this strong privacy guarantee can be upheld while achieving spectral clustering convergence rates that match the known rates without privacy.

Article Synopsis
  • Recurrent dizziness and vertigo can stem from conditions like vestibular migraine (VM) or vestibular neuritis/labyrinthitis (VN/L), which may present similar symptoms and require thorough evaluation for accurate diagnosis.
  • A study analyzed the Vestibulo-Ocular Reflex Time Constants (VORT) using rotary chair testing in 68 patients diagnosed with either VM or VN/L to aid in differentiating between these two conditions.
  • Results indicated that patients with VM had significantly higher VORTs compared to those with VN/L, suggesting that VORT measurements can be a valuable tool in diagnosing central versus peripheral vestibular issues.
