GRIA2 and Hypoglycemia: Many intrahippocampal subnetworks are characterized by high densities of GluA1/2 and GluA2/3 receptors.17 A particularly vulnerable area is the CA1 sector, which is highly sensitive to hypoxia of diverse toxic or metabolic conditions, such as hypoglycemia or abuse of psychostimulant drugs.18 Neuropathologic investigation of the brain in our patient revealed unilateral hippocampal sclerosis affecting the CA1 and CA4 regions of the hippocampus.
