Application
CNQX has been used:
- as an α-Amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA)/kainate blocker to study its effects on cytoneme formation in pluripotent embryonic stem cells (pESCs)
- glutamate blocker to reduce the synaptic input during current-clamp recordings in central antennal lobe neurons
- as a non-N-methyl-D-aspartate (NMDA) receptor blocker to study its effects on the heart rate in rats
Biochem/physiol Actions
Potent, competitive AMPA/kainate glutamate receptor antagonist.

Long-term depression (LTD) of synaptic efficacy is widely regarded as a cellular basis of learning and memory. The magnitude of hippocampal CA1 LTD induced by low-frequency stimulation (LFS) declines with age, but the mechanisms involved remain poorly understood. Perineuronal nets

The study of human cortical development has major implications for brain evolution and diseases but has remained elusive due to paucity of experimental models. Here we found that human embryonic stem cells (ESCs) and induced pluripotent stem cells (iPSCs), cultured

Oligodendrocyte (OL) maturation and axon-glial communication are required for proper myelination in the developing brain. However, physiological properties of OLs remain largely uncharacterized in different brain regions. The roles of oligodendroglial voltage-activated Na+ channels (Nav) and electrical excitability in relation
