Using downstream glial and amyloid/tau biomarkers (plasma p-tau217, GFAP, NfL, amyloid PET, cytokine panels, TSPO PET, microglial scRNA-seq) as pharmacodynamic readouts after gamma/tFUS. NOT claiming that gamma directly normalizes APOE4 or TREM2 transcription as a primary causal mechanism. Gamma entrainment may reduce neuronal damage and downstream glial activation indirectly; APOE/TREM2 expression changes should be exploratory, not the central thesis.
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.
Convergent vs Divergent Predictions
