This hypothesis proposes using closed-loop transcranial focused ultrasound (tFUS) to selectively activate somatostatin-positive (SST) interneurons in entorhinal cortex layer II as an upstream intervention to restore hippocampal gamma oscillations in Alzheimer's disease. The approach leverages mechanosensitive ion channel activation (PIEZO1/TREK-1) in EC-II SST interneurons through precisely timed ultrasonic stimulation, triggering SST release and creating gamma-frequency entrainment at 30-80 Hz

## Molecular Mechanism and Rationale Somatostatin-positive (SST+) interneurons in entorhinal cortex layer II provide critical GABAergic inhibition that regulates the excitability of stellate cells and controls the temporal dynamics of perforant path output to the hippocampus. Early tau hyperphosphorylation disrupts the intrinsic membrane properties and synaptic function of SST interneurons, leading to disinhibition of layer II stellate cells and aberrant gamma oscillations in the 30-80 Hz range
