## Molecular Mechanism and Rationale
Vasoactive intestinal peptide (VIP) interneurons regulate cortical circuit dynamics through selective disinhibition of pyramidal neurons via inhibition of parvalbumin-positive (PV+) and somatostatin-positive (SST+) interneurons. VIP neurons express G-protein coupled receptors (VPAC1 and VPAC2) that, when activated by endogenous VIP, trigger cAMP-dependent protein kinase A signaling cascades leading to enhanced GABA release and modulation of local inhibitory
This hypothesis proposes that GluN2B-containing NMDA receptors in thalamocortical circuits directly regulate glymphatic system function through control of astrocytic aquaporin-4 (AQP4) polarization and cerebrospinal fluid flow dynamics. The mechanistic framework centers on thalamocortical gamma oscillations, which are critically dependent on extrasynaptic GluN2B receptors, serving as the primary driver of astrocytic calcium waves that maintain proper AQP4 clustering at perivascular endfeet.
