The GluN1 subunit of the NMDA receptor shows age-related changes in its
expression pattern, some of which correlate with spatial memory performance in mice.
Aged C57BL/6 mice show an age-related increase in mRNA expression of GluN1
subunit splice variants that lack the N terminal splice cassette, GluN1ₒₓₓ (GluN1-a). This
increase...
