Restored gamma oscillations decrease pro-inflammatory microglial activation in EC via CRHR1-mediated SST release from interneurons binding to microglial SSTR2, suppressing NF-κB signaling and IL-1β/IL-6 release. The CRHR1-SST-SSTR2 axis is speculative; CRHR1 expression on EC-II SST interneurons is not established. Use as secondary downstream readout, not standalone mechanism.
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
This summary checks where the selected hypotheses point toward the same target or mechanism, and where they pull in opposite directions.
