Cannabinoids are small molecules that act on receptors in the brain. They also inhibit excitatory signals. Inhibiting these signals inhibits the DSE. Researchers Anatol Kreitzer and Wade Regehr studied cerebellar slices and found that cannabinoids inhibit excitatory signals. They tried identifying the messenger responsible for initiating DSE and found that blocking the cannabinoid signals wholly wiped out the effects.

Interact with Receptors
Cannabinoids interact with receptors throughout the brain in ways that differ from other neurotransmitters. Neurotransmitters are chemicals released from neurons to coordinate motor and cognitive functions. After leaving presynaptic cells, these chemicals travel across the synapse and attach to receptors on nearby neurons. The receiving neuron then transmits a message to other nearby neurons. The endocannabinoid system helps to regulate the release of neurotransmitters and synaptic plasticity. But unlike other neurotransmitters, cannabinoids interact with the endocannabinoid system differently.
There are two types of cannabinoid receptors, CB1 and CB2 receptors. The CB1 receptor is expressed on neurons, astrocytes, microglia, and oligodendrocytes, which are responsible for synaptic transmission.
Two major endocannabinoids, 2-arachidonic acid and anandamide, are released from the postsynaptic terminals. These compounds travel back to the presynaptic neuron, which attaches to cannabinoid receptors. This allows them to regulate neurotransmitter release and calcium influx.
Aside from interacting with the endocannabinoid system, cannabinoids are also known to stimulate appetite. The mechanism for this effect is CB1R-dependent. Cannabinoids have been demonstrated in studies to enhance endocannabinoid levels in the hypothalamus while fasting and reduce them after food consumption. When CB1Rs are inhibited, the appetite-stimulating effect is abolished.
Two major endocannabinoids, 2-AG and AEA, have distinct receptor-binding properties. AEA has been shown to interact with TRPV1 and CB2R, which are involved in synaptic transmission and pain regulation. 2-AG, on the other hand, interacts with non-CBRs. However, these two substances share significant differences in receptor selectivity, and they are synthesized and transported differently in their target tissues. Cannabinoids have been demonstrated in studies to enhance endocannabinoid levels in the hypothalamus while fasting and reduce them after food consumption.

Reduce Excitatory and Inhibitory Signals
The ability of cannabinoids to suppress excitatory and inhibitory signals in the human brain makes them potentially valuable drugs for various disorders. One such disorder is epilepsy. During seizures, pyramidal cells fire out of control, possibly because inhibitory interneurons shut down. The ability of cannabinoids to silence pyramidal cells could lead to new treatments for this disorder.
Researchers have found that cannabinoids may help reduce the symptoms of multiple sclerosis and spasticity. They also found that cannabinoids reduced anxiety in social phobia patients. These findings were published in the journal Neuropsychopharmacology.
The endocannabinoid system influences appetite and reward by modulating the brain’s glutamate, GABA, and dopamine levels. By reducing the amount of inhibitory and excitatory signals in the brain, cannabinoids decrease avoidance behavior and increase appetitive responses to rewarding stimuli, such as food or drug abuse.
Cannabinoids also have a role in the regulation of gastrointestinal functions. For example, the endocannabinoid system mediates fat intake and hunger signaling. These interactions also involve the gut microbiota. By reducing the levels of GABA in the gut, cannabinoids temporarily reduce the release of inhibitory molecules from interneurons.
Research on the pharmacological effects of cannabinoids is still ongoing. Research on the mechanisms of these compounds will help us make better medications and control their side effects and risks.
Increase Dopaminergic Neurons
The constituents of the cannabis plant, including THC and CBD, affect the human body in various ways. In particular, these chemicals interact with the endocannabinoid system (ECS), which regulates various physiological processes. In the brain, components of the ECS are found in dopaminergic neurons. These substances serve as traffic controllers, and unlike many neurotransmitters, they travel retrogradely – from presynaptic to postsynaptic neurons.
These chemicals increase dopamine neurotransmission in the brain by increasing the concentrations of the neurotransmitter dopamine and decreasing the amount of dopamine that is reabsorbed. Specifically, cannabinoids increase the width of electrically evoked dopamine release events, leading to high dopamine concentrations and saturation of dopamine transporters.
The dopamine system is believed to be responsible for goal-directed behavior. As a result, when humans anticipate receiving a reward, their DA neurons fire with an increased frequency. This increased frequency enables the anticipation of reward to trigger a burst of dopamine release, leading to the desired outcome. This is known as Pavlovian classical conditioning. Studies have shown that exogenous cannabinoids enhance dopamine release by stimulating appetite. These findings suggest that cannabinoids may help patients achieve weight gain.
The endocannabinoid D9-tetrahydrocannabinol, the primary psychoactive component of cannabis Sativa, increases dopamine levels in the terminal regions of the mesolimbic dopamine system. This system originates from the ventral tegmental area of the midbrain. It projects into limbic structures, including the nucleus accumbens, the primary reward area in drug abuse.
