Age‐associated changes in the expression of NMDA receptors freely solubilize subunits in the cortical rat tissue homogenate. A representative Western blot for NMDA receptors subunits in the cerebral cortex in (a); and in (b) quantified results for GluN1, GluN2A, and GluN2B expressions in young and aged rats (n = 5). Data are expressed as mean (±SEM) normalized to young rats, with each data point representing a duplicate from one animal. Data were analyzed using an unpaired t‐test. *p ≤ 0.05. NMDA, N‐methyl‐d‐aspartate).
