The mechanistic chain—tau → HCN1 dysfunction → impaired dendritic integration → theta-gamma decoupling → spatial navigation deficits—represents a plausible disease pathway supported by established AD neurobiology.\n\n**Mechanistic strengths:**\n- Links established tau pathology to measurable electrophysiological endpoints\n- Focuses on EC layer II, a region critically affected early in AD\n- Positions HCN channels as downstream effectors rather than primary targets\n- Acknowledges the distinct functional roles of SST (dendritic) vs. PV (perisomatic) interneurons\n\n**Critical mechanistic concern:**\nThe claim that \"hyperphosphorylated tau directly binds to and disrupts HCN1 channel trafficking\" represents the",
