EC-II SST interneuron inhibition of PV+ basket cells paradoxically enhances gamma power through synchronized peri-somatic disinhibition—requires explicit circuit-level validation in EC-II slice preparations before proceeding to tFUS validation. Keep as mechanistic biology experiment ONLY; NOT a development-grade therapeutic rationale. Requires direct electrophysiological evidence in identified EC-II SST→PV connections, not inference from CA1 data.
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.
