Hypothesis

Closed-Loop Hippocampal TFUS for Gamma Network Target Engagement

The debate converges on closed-loop transcranial focused ultrasound (TFUS) targeting hippocampal network oscillations (gamma power, theta-gamma coupling) as the core viable program.

🧪 Overview

The debate converges on closed-loop transcranial focused ultrasound (TFUS) targeting hippocampal network oscillations (gamma power, theta-gamma coupling) as the core viable program. The critical unresolved question is whether CCK interneurons are the necessary and sufficient mediators. H1 represents the most fundamental testable hypothesis, but CCK-specificity remains an unproven assumption. The surviving translational concept is narrower: closed-loop hippocampal TFUS as a device-based neuromodulation strategy to restore pathologic network rhythms in early AD, with CCK interneurons treated as a mechanistic candidate, not the clinical target.
