SNI selectively increases GluA1 levels at the synapse of the shell subregion of NAc. A, SNI resulted in an increase in GluA1 subunits in the synaptoneurosomes of NAc shell. Student’s t test, n=12, * p<0.05. B, SNI caused no changes in GluA2 subunits at the synapse. n=12, p>0.05. Data were normalized to values in the sham group.
