Comparing 2 hypotheses side-by-side
## Mechanistic Overview Default Mode Network Circuit Stabilization starts from the claim that modulating VIP within the disease context of neuroscience can redirect a disease-relevant process.

## Mechanistic Overview This hypothesis proposes using closed-loop transcranial focused ultrasound (tFUS) to selectively activate somatostatin-positive (SST) interneurons in entorhinal cortex layer II (EC-II) as an upstream intervention to restore hippocampal gamma oscillations in Alzheimer's disease. The approach leverages mechanosensitive ion channel activation (PIEZO1/TREK-1) in EC-II SST interneurons through precisely timed ultrasonic stimulation, triggering SST release and creating gamma-f
