Oscillatory Coupling Between Thalamus, Cerebellum, and Motor Cortex in Essential Tremor
Movement Disorders, Volume 40, Issue 5, Page 896-905, May 2025.Abstract Background Essential tremor is hypothesized to emerge from synchronized oscillatory activity within the cerebello‐thalamo‐cortical circuit. However, this hypothesis has not yet been tested using local field potentials directly recorded from the thalamus alongside signals from both the cortex and cerebellum, leaving a gap in the understanding ...

Advancements in the GRACE and GRACE‐FO Gradiometer Mode
Earth and Space Science, Volume 12, Issue 5, May 2025.Abstract The global gravitational gradient field has not been observed since the decommission of GOCE in 2013. Based on the foundational work of Peidou and Pagiatakis (2019, https://doi.org/10.1029/2018jb016382), we advance the concept of GRACE gradiometer mode (GM) for the purpose of using GRACE, GRACE‐FO and future gravity space missions as ...
