Aβ accumulation in EC disrupts layer II stellate cell projections to dentate gyrus, fragmenting theta-phase precession and theta-gamma coupling. A closed-loop optogenetic system detecting EC-driven theta inputs and providing precisely timed PV interneuron activation in dentate gyrus can re-align the EC-hippocampal temporal window. The critical weakness is circuit complexity: Aβ also disrupts EC layer III pyramidal inputs to CA1; layer-specific targeting may not address all TGc deficits. Evidence for layer II dysfunction as the primary driver is insufficient.
