L-Glutamic acid monosodium salt
Based on 15 publication(s) in Google Scholar
L-Glutamic acid monosodium salt is an excitatory amino acid neurotransmitter that acts as an agonist for all subtypes of glutamate receptors (metabolic rhodophylline, NMDA, and AMPA). L-Glutamic acid monosodium salt has an agonist effect on the release of DA from dopaminergic nerve endings. L-Glutamic acid monosodium salt can be used in the study of neurological diseases. L-Glutamic acid monosodium salt acts at ionotropic and metabotropic glutamate receptors.

L-Glutamic acid (100 µM; 10 min) for activation of spike count. Spontaneous LFP activity is recorded from OPAB that has been pre-treated with Bicuculline and stimulated with L-Glutamic acid. The LFP signal from the activated OPAB is measured (pre), and then the electrical signal is inhibited for 10 min using a cocktail of TTX, CNQX, and AP5 and LFP was recorded again (post).
