Comparing 2 hypotheses side-by-side
## Mechanistic Overview Closed-loop transcranial focused ultrasound to restore hippocampal gamma oscillations via glymphatic enhancement and amyloid clearance from PV interneurons in Alzheimer's disease starts from the claim that modulating PVALB within the disease context of Alzheimer's disease can redirect a disease-relevant process. The original description reads: "**Molecular Mechanism and Rationale** The therapeutic mechanism centers on the intricate interplay between glymphatic system enha
## Mechanistic Overview Closed-loop transcranial focused ultrasound with 40Hz gamma entrainment to restore hippocampal-cortical connectivity in early MCI starts from the claim that modulating PVALB within the disease context of Alzheimer's disease can redirect a disease-relevant process. The original description reads: "**Molecular Mechanism and Rationale** The proposed closed-loop transcranial focused ultrasound (tFUS) with 40Hz gamma entrainment targets a fundamental pathophysiological circuit
