🧪 Overview

Thalamocortical circuits interface with para-arterial glymphatic influx pathways while corticopial projections interface with venous efflux. GluN2B-mediated thalamic activity preferentially shunts CSF toward deeper thalamocortical perivascular spaces; reduced GluN2B redirects flow superficially. Tau clearance efficiency depends on matching regional burden to appropriate drainage topology.
