The Role of Neurotransmitters in Healthy Brain Functioning
In simple words, neurotransmitters are chemical messengers that boost brain functioning. There are a variety of neurotransmitters in the body, and since each is responsible for an intricate task to perform, students find it difficult to remember each one. Therefore, they acquire the best coursework writing service from online sources. However, to minimise the financial load of students, a detailed description of some of the most important neurotransmitters is presented below.
• Gamma-aminobutyric acid (GABA)
Gamma-aminobutyric acids are considered to be an extremely important part of your brain. They are responsible for several functions, and some of them include; control of the vision and motor pathways, regulation of anxiety, and maintaining calmness in the body. Thus, if you’re a psychology or psychiatry student, you must have learned about its role in reducing anxiety.
Benzodiazepines are an extensive line of drugs that are comprised of this acid. And this drug is prescribed to patients with severe anxiety disorders. Hence, they regulate and calm the body when it is alert and uncontrollable.
This is one neurotransmitter that is found in abundance in the human body. This neurotransmitter is responsible for the maintenance of memory and learning. However, if it is found in an excessive amount, it can be fatal for the person. Additionally, if there is a lack of regulation, then it can cause Alzheimer’s disease, epileptic seizures, strokes, etc.
Oxytocin is fairly popular among people and is very commonly used during conversations. Since it is a hormone as well as a neurotransmitter, it is known for its role in pregnancy. In addition to this, this multi-tasker is significant in terms of sexual reproduction, social connection, and recognition. It basically holds paramount importance during the delivery period as it helps in reducing the labour pain.
Again, this is another popular neurotransmitter that has earned quite a reputation due to its role in causing euphoria. Fitness experts, athletes, and doctors always speak prominently about the features and traits of endorphins. As mentioned, it is responsible for causing euphoria, so it is also known as the happy hormone. When a person exercises or moves body causing it to sweat, endorphins are released. Thus, they help in reducing stress levels. A lesser-known fact about this neurotransmitter is that it also helps in relieving pain.
Often termed as the adrenaline hormone, epinephrine is also a neurotransmitter. The most prominent role of this neurotransmitter is that it reduces stress levels. Usually, people associate cortisol when they speak of stress levels, but it is epinephrine that helps in dealing with the flight and fright response. When the adrenaline rush kicks in, epinephrine is at its peak.
Another neurotransmitter that has a significant part to play in the flight and fright response is norepinephrine. Hence, whenever your body finds itself in places of danger or threat, this neurotransmitter mobilises it. The time when the levels of this neurotransmitter are the lowest is during sleep. Let’s speak say that when you’re calm and collected, and you’re not under any stress, the levels of norepinephrine is the lowest.
Dopamine is often associated with recreational drugs. They are responsible for increasing focus and bringing efficiency in life. They help in spatial movements like coordination of the muscles. Additionally, they have a fair share in developing motivation in the body. Hence, in regards to the social rewards system and the build-up of motivation, the name of dopamine comes at the top. The loss of dopamine can lead to Parkinson’s disease and body tremors.
Another neurotransmitter that is popular on the list is Serotonin. Whenever you feel sad, the level of serotonin decreases in the body. Hence, depression, anxiety, and bipolar are all causes of the dysregulation of serotonin in the body. To treat these disorders, the psychiatrists always prescribe selective serotonin reuptake inhibitors as they help in redeeming the amount of serotonin in the body.
Acetylcholine is primarily associated with motor functioning of the body. It is found in both the peripheral nervous system and the central nervous system. In addition to this, it has a significant part to play in jogging down memory and enhancing learning abilities.
Thus, it can be established that the brain is wired in a far more complex manner than we imagine. To understand a human brain, it is important first to comprehend the basic role of each neurotransmitter.
