Excitatory synaptic transmission in the brain is predominantly mediated by the neurotransmitter glutamate, while inhibitory transmission is mediated mainly by the neurotransmitter gamma-amino butyric acid (GABA). (frontiersin.org)

Autism Spectrum Disorder (ASD) is a synaptic disorder with a GABA/glutamate imbalance in the perineuronal nets and structural abnormalities such as increased dendritic spines and decreased long distance connections. (bvsalud.org)
Postsynaptic8
This can lead to changes in the synapse's excitability, for example by presynaptic inhibition of neurotransmission, or modulation and even induction of postsynaptic responses. (wikipedia.org)
Their action can be excitatory, increasing conductance, causing more glutamate to be released from the presynaptic cell, but they also increase inhibitory postsynaptic potentials, or IPSPs. (wikipedia.org)
These receptors are involved in presynaptic inhibition, and do not appear to affect postsynaptic membrane potential by themselves. (wikipedia.org)
Receptors in groups II and III reduce the activity of postsynaptic potentials, both excitatory and inhibitory, in the cortex. (wikipedia.org)
For example, one study found that Group I mGluRs are located mostly on postsynaptic parts of cells, while groups II and III are mostly located on presynaptic elements, though they have been found on both pre- and postsynaptic membranes. (wikipedia.org)

Dopamine receptors3
In the next series of experiments, coapplication of dopamine and 1 S ,3 R -ACPD, but not application of either drug alone, consistently induced LTD without tetani or even single test stimuli during drug application, suggesting that coactivation of dopamine receptors and the mGluRs is sufficient for LTD induction. (jneurosci.org)
Immunoblot analyses with anti-active mitogen-activated protein kinases (MAP-Ks) revealed that D1 receptors, D2 receptors, group I mGluRs, and group II mGluRs all contribute to MAP-K activation in prefrontal cortex, and that combined activation of dopamine receptors and mGluRs synergistically or additively activate MAP-Ks.

GABA4
The maximal level of enhancement seen with either CBD or 2-AG were on α2-containing GABAA receptor subtypes, with approximately a 4-fold enhancement of the GABA EC5 evoked current, more than twice the potentiation seen with other α-subunit receptor combinations. (researchgate.net)
Exploration of extrasynaptic α4β2δ receptors revealed that both compounds enhanced GABA EC5 evoked currents at concentrations ranging from 0.01-1 μM. (researchgate.net)

In this regard, CBD inhibition of 5-HT 3 receptors may contribute to its role in modulation of nociception and emesis, potentiation of GABA receptors may account for its anti-seizure, anxiolytic and analgesic effects, and potentiation of glycine receptors may be relevant for CBD anti-nociceptive actions [3,16, 22] .

Positive allosteric modulators2
Several subtype-selective positive allosteric modulators that activate only the mGlu2 subtype, such as Biphenylindanone A, have also now been developed. (wikipedia.org)
