To investigate whether excitatory nerve terminals projecting to PAG neurons express functional glycine receptors and whether the activation of presynaptic glycine receptors directly modulates spontaneous glutamate release, we observed the effect of exogenously applied glycine on sEPSCs.
Several lines of evidence suggest that glycine receptors are also expressed on excitatory nerve terminals projecting to PAG neurons and that their activation enhances spontaneous glutamate release onto PAG neurons.
The compound selectively antagonizes the AMPA receptor, a type of receptor to which the neurotransmitter glutamate binds, and by preventing the excessive influx of calcium into brain cells, it suppresses the overactivity of excitatory nerves, thereby correcting excitatory-inhibitory nerve imbalance and inhibiting neuronal cell death.
