• despite altered glutamatergic receptor levels, mice exhibit normal glutamatergic synapse formation, paired pulse facilitation, synaptic and extrasynaptic AMPAR responses, and long-term potentiation
decreased brain size ( J:146603 )
• at 3 weeks, brain volume is slightly decreased compared to in wild-type mice
• however, by 7 months of age mice exhibit normal brain volume
