Kainate receptors, or kainic acid receptors, are ionotropic receptors that respond to the neurotransmitter glutamate. They were first identified as a distinct receptor type through their selective act

5-Fluorowillardiine is a selective agonist for the AMPA receptor, with only limited effects at the kainate receptor. It is an excitotoxic neurotoxin when used in vivo and so is rarely used in intact a
