Closed-loop transcranial focused ultrasound targeting CA1 PV interneurons with real-time gamma feedback to prevent tau propagation and restore hippocampal-prefrontal synchrony in Alzheimer's disease
h-var-ee70969116
## Molecular Mechanism and Rationale
Parvalbumin-positive (PV+) fast-spiking interneurons in the hippocampal CA1 region express mechanosensitive ion channels including PIEZO1 and TREK-1 that respond to focused ultrasound-induced acoustic pressure waves through membrane deformation and cytoskeletal tension changes. Upon mechanostimulation, these channels facilitate calcium and potassium flux, lead
