GABA And Glutamate New Developments In Neurotransmission Researc. (intechopen.com)
These neurons are believed to release GABA, not glutamate, as their neurotransmitter (Yazulla, 1986), suggesting the weak glutamate labeling reflects the pool of metabolic glutamate used in the synthesis of GABA. (org.es)
This has been supported by the results from double-labeling studies using antibodies to both GABA and glutamate: glutamate-positive amacrine cells also label with the GABA antibodies (Jojich and Pourcho, 1996, Yang, 1996). (org.es)
In addition to this GABA-ergic effect, barbiturates also block the AMPA receptor, a subtype of glutamate receptor. (illumina.com)
