6/ This project started before COVID and demonstrates the power of turning 🦠bugs into features. The unplanned long spacing between recording sessions demonstrated decoder stability across >2 years WITHOUT retraining, a major boon for future BCI applications.

5/ 🔍 These mesoscopic patches enable robust decoding of multiple movement directions! To confirm this, we coded a cortical-based searchlight analysis for fUSI data that reveals the neurovasculature most important for decoding performance.

4/ 🔍 Small mesoscopic (~100-400 μm) patches of lateral intraparietal cortex (LIP) robustly encode for different movement directions, with >10-20% changes in the underlying neurovasculature!

3/ 🔍 This latest paper showcases how functional ultrasound imaging (fUSI) can capture intricate brain activity with high resolution. It offer insights into how the brain orchestrates eye movements, critical for understanding sensory and motor integration.

Functional ultrasound neuroimaging reveals mesoscopic organization of saccades in the lateral intraparietal area - Nature Communications
The functional organization of the posterior parietal cortex (PPC) for guiding eye movements has remained unknown. Here, the authors use functional ultrasound neuroimaging to reveal small, tuned clusters in PPC that reliably encode where we look over months to years.
