Everything about Neurotransmitters

Neurotransmitters are the chemicals in the brain which trigger every kind of reaction. Not all neurotransmitters have been discovered, and the research is still going on in order to understand and figure out which neurotransmitter performs what function.

What Neurotransmitters Are Most Renowned?

Since the beginning of brain chemistry, one by one, four major brain chemicals or neurotransmitters were discovered. They each play a different role, and each brings about a different reaction in our brain. Geniux reviews have demonstrated its role in neurotransmitters.  The four neurotransmitters are GABA, acetylcholine, dopamine, and serotonin.

  • GABA is the neurotransmitter which is responsible for inducing calm in the racy thoughts of the brain
  • Acetylcholine is responsible for memory and other cognitive functions
  • Dopamine gives the body the necessary motivation to do tasks in life
  • Lastly, Serotonin is the most popular neurotransmitter as it often called as the Happy molecule


This neurotransmitter is extremely popular among the other brain chemicals. This neurotransmitter is believed to be responsible for the happiness of the entire body. However, there is no known research to back the hypothesis; it is just accepted that serotonin induces happiness in a person.

This is the reason why anti-depressants usually contain chemicals that trigger the production of serotonin. However, since it is just a hypothesis, the drugs work as well as a placebo can work. The drugs rely on the patient’s neural system.

Tryptophan is the chemical precursor and amino acid is the building block for serotonin. But drugs do not work as well as they should on the production of tryptophan and, in turn, serotonin. Instead, natural remedies of serotonin production are more effective.


This neurotransmitter was the first chemical to be identified inside the brain. It is extremely important as it deals directly with the intellectual capabilities of a person. Therefore, if the levels of acetylcholine drop, they will cause huge memory problems.

This is the reason why Alzheimer’s patients lose about 90% of their mental capacities. Also, reduction in the levels of Acetylcholine causes a disturbance in focus, memory, dizziness and insomnia. In severe cases, the brain starts eating itself up to make up for the reduced levels of acetylcholine.

People are usually advised to consume high-fat content foods as acetylcholine production depends on the fat content in the body. Fish, meat, poultry and milk products need to be incorporated in a person’s diet so that a person receives adequate amounts of acetylcholine.


Research shows that lab mice that lack sufficient levels of dopamine will invariably starve to death rather than consume food. Hence, dopamine is called as the motivation molecule in brain chemistry. Low energy, motivation, low libido are all signs of low dopamine levels.

Thrill seekers and drug addicts are ones who never have a low level of dopamine; natural methods of getting a hike in levels is via coffee, nicotine and other recreational drugs.


It is extremely necessary to make sure that the brain gets itself some rest. It dampens down the brain activity bringing about an invariable tranquillity to the person. A diet comprising of fermented foods, organs, and lentils, etc. give a hike in GABA levels.

It is believed that urine tests can be an indicator of the neurotransmitter levels in the brain. But it isn’t so because brain and body levels of neurotransmitters are not connected and independent of each other.
