Successful block of ion flow through NMDA receptors
By Anonymous on 10/20/2017

We used this drug in bath application to block ion flow through NMDA receptors and observe dendritic spine structural plasticity int he absence of ion flow.

We incubate with this drug for at least 30 minutes before use. We are using cultured hippocampus slices.
