As a layman, I would like to know if there are different subgroups of
NMDA-receptors in different parts of the human body. Most of all, I
would like to know if the NMDA-receptors in the human cochlea differ
from the NMDA-receptors in the brain. Is there any theoretical
possibility to create an NMDA-antagonist that only works in the
cochlea while avoiding side-effects in the brain?
Thank you very much for your help!
