Comparing 2 hypotheses side-by-side
# Synaptic Pruning Precision Therapy: Targeting Complement and Chemokine Signaling to Preserve Neuronal Connectivity ## Scientific Background Synaptic pruning represents a developmentally regulated process whereby immature or redundant synaptic connections are selectively eliminated to refine neural circuitry. While essential during early postnatal development, aberrant or excessive pruning has emerged as a pathological hallmark in multiple neurodegenerative conditions, including Alzheimer's
## Mechanistic Overview Closed-loop transcranial focused ultrasound targeting EC-II SST interneurons to restore hippocampal gamma oscillations via upstream perforant path gating in Alzheimer's disease starts from the claim that modulating SST within the disease context of Alzheimer's disease can redirect a disease-relevant process. The original description reads: "## Mechanistic Overview Closed-loop transcranial focused ultrasound targeting EC-II SST interneurons to restore hippocampal gamma osc
