Effects of Modafinil on Dopamine Transporters in the Human Brain


This article describes the effects of Modafinil on dopamine transporters in the human brain. It highlights the role of increased dopamine levels in the nucleus accumbens. It concludes that Modafinil enhances the function of these neurotransmitters. However, further research is need to understand exactly how Modafinil affects dopamine transporters in the human brain.

Increased dopamine levels in nucleus accumbens

The nucleus accumbens is part of the brain’s reward circuit. When we experience something pleasurable, dopamine neurons in the ventral tegmental area activate, project to, and increase dopamine levels in the nucleus accumbens. This pathway supplies dopamine to the pituitary gland, where it inhibits the production of prolactin.

In a recent study, researchers showed that deep brain stimulation of the nucleus accumbens decreased depression and anxiety ratings in treatment-resistant depressed patients. Further, this deep brain stimulation reduced anxiety and depression ratings in depressed people who had been unsuccessful in treating their symptoms with traditional therapies.

In this medicine Modafinil is active ingredient.

Increased Dopamine

Increased dopamine levels in the nucleus accumbens are linked to the development of addiction. The nucleus accumbens is a brain region that links reward desire to motor response. As such, it is critical to understand how this neurotransmitter contributes to addiction. The nucleus accumbens releases dopamine in response to both aversive and rewarding stimuli.

Researchers found that the interaction between dopamine and cannabinoid agonists may contribute to the development of CNS disorders. Researchers from the University of California at San Diego reported findings in the journal CNS Neurosis Researchers from the University of California, San Diego, and the University of Southern California collaborated on the study. California, found that the c-fos gene was activate during rough play among juvenile rats.

Extracellular Dopamine

In vivo microdialysis studies revealed that cocaine and amphetamine increased dopamine levels in the medial prefrontal cortex. These findings back with prior research that suggests dopamine has a role in centra reinforcement processing. They also discovered that administration of substance P to the nucleus basalis magnocellular is (which controls place preference) increased the levels of extracellular dopamine in the contralateral nucleus accumbens. Moreover, these studies revealed that only animals with increased dopamine levels acquired place preference.

Dopamine is a neurotransmitter that has an excitatory and inhibitory effect on neurons. The type of effect it has on a target neuron depends on the receptors on the cell’s membrane. This is the first time researchers have linked the two compounds to different types of behavior. They show that dopamine increases the level of cAMP in the target neurons.

Dopamine Activity

Moreover, increased dopamine levels in the nucleus accumbens have a positive impact on social play. This study suggests that increased dopamine activity in the nucleus accumbens (NAc) may underlie social impairments in a variety of developmental psychiatric disorders, including autism and early-onset schizophrenia. However, further research is need to confirm this hypothesis.

The NAc contains medium spiny neurons with high GABA-receptor density. These neurons also interact with dopaminergic, glutamatergic, and glutamatergic medium spiny projection neurons. The activity of these neurons is control by glutamatergic and cholinergic afferents in the frontal cortex and the amygdala.

Although the DA levels in the nucleus accumbens are higher after noxious stimulation, the effect is smaller when innocuous mechanical stimulation is used. Moreover, it does not affect the release of noradrenaline or serotonin. The increase in DA secretion in the nucleus accumbens is consistent with its role as a relay in the reward system of the brain.

Neurotransmission Studies

Neurotransmission studies of the NAc have shown that glutaminergic neurons in the PVT may contribute to increased dopamine levels in the NAc in conscious animals. In addition, glutaminergic neurons in the PVT stimulate dopaminergic neuronal terminals and are believed to be involved in the release of dopamine. The results indicate that glutaminergic neuronal inputs may play a major role in the reward effect. Visit
