Low-intensity tFUS acutely modulates entorhinal-hippocampal transmission and plasticity at EC-DG and EC-CA1 synapses in AD-relevant circuits. WITHOUT claiming SST interneuron or Piezo1/TRPML1 specificity. The mechanistic hypothesis should be simplified: tFUS → neural activity modulation → synaptic strengthening at perforant path inputs. Requires GsMTx4-independent validation (conditional Piezo1 KO) and comparison to sham ultrasound in identified circuits.
Delivering 40 Hz (gamma) tFUS or sensory entrainment adaptively synchronized to real-time theta phase detection to restore theta-gamma coupling, reduce network hyperexcitability, and enhance memory encoding in early AD. NOT targeting EC-II SST interneurons specifically—cell-type targeting is not currently feasible with non-invasive neuromodulation. Primary target engagement readout: hippocampal/entorhinal gamma power and theta-gamma coupling via EEG/MEG.
