31. One of the major neurotransmitters involved in conditioned fear learning is glutamate . 32. Glutamate activates NMDA and AMPA receptors which produce action potentials.33. Other common conditions that cause excessive glutamate concentrations around neurons are hypoglycemia. 34. This family includes : glutamate , glutamine, proline, and arginine. 35. In experiments, it is used to counter glutamate excitotoxicity. 36. It can be chili, in place of monosodium glutamate . 37. GABA and glutamate often interact with each other and with dopamine directly. 38. Signals including glutamate from axon branches may increase branch additions. 39. Astrocytes protect neurons against excitotoxicity by taking up excess ammonia and glutamate . 40. Alanine, glycine, and serine bind to the glutamate substrate site.
