Aβ oligomers downregulate KCNQ2/3 voltage-gated potassium channels on PV interneurons via PKC-dependent phosphorylation, reducing accommodation and impairing theta-frequency resonance. Pharmacological or optogenetic restoration of M-current kinetics reinstates theta rhythmicity. This hypothesis benefits from the strongest pharmacological precedent (retigabine already shown effective in Tg2576 mice) but the optogenetic ChR2-proposed component is mechanistically inelegant—sustained depolarization
Closed-loop stimulation of PV+ interneurons at gamma frequencies (40 Hz) using ChrimsonR rescues gamma oscillation power reduced by Aβ oligomers. Sustained 40 Hz optogenetic entrainment promotes activity-dependent upregulation of PV protein and GAD67, recovering inhibitory tone onto pyramidal neurons. The Skeptic identified a critical experimental design flaw: the Theorist's proposal uses hSyn1-ChrimsonR which drives expression in all excitatory neurons, not specifically PV interneurons. This ce
