## Molecular Mechanism and Rationale Somatostatin-positive (SST+) interneurons in entorhinal cortex layers II-III provide dendritic inhibition that controls excitatory integration and theta-gamma coupling through precise regulation of hyperpolarization-activated cyclic nucleotide-gated (HCN) channels on stellate cell dendrites. In Alzheimer's disease, hyperphosphorylated tau directly binds to and disrupts HCN1 channel trafficking and membrane insertion in SST interneuron dendrites, leading to a
## Molecular Mechanism and Rationale Somatostatin-positive (SST) interneurons in entorhinal cortex (EC) layer II serve as critical gamma frequency gatekeepers that regulate perforant path transmission to the hippocampus through perisomatic inhibition of stellate cells. These parvalbumin-negative interneurons express voltage-gated calcium channels and mechanosensitive ion channels that respond to low-intensity focused ultrasound (LIPUS) through sonoporation-mediated calcium influx and subsequent
