What is DOPAMINE: Definition and Functions

You have probably heard about dopamine at some point since it is an increasingly popular neurotransmitter due to the relationship it has with well-being, which is why it is commonly known as one of the “hormones of happiness.” Dopamine is a neurotransmitter of the central nervous system that acts as a chemical messenger and regulates very important functions for the body such as memory, sleep, mood, heart rate, motor activity, cognition and behavior. It is important for all human beings to maintain an adequate level of this substance in our brain since when this is not the case and the natural secretion of dopamine is affected, this can have certain consequences such as the appearance of some diseases such as Parkinson’s and drug addiction. among others. In this Psychology-Online article: What is dopamine: definition and functionswe are going to tell you in detail everything about this neurotransmitter.

Dopamine: definition

Dopamine is a neurotransmitter which performs various functions in people and other animals. It is a tiny molecule that is made up of 22 atoms and is produced by less than 1% of neurons. Regarding the location of this neurotransmitter, it is found in the substantia nigra of the midbrain and in its prefrontal area. The prefrontal area of ​​the brain is responsible for carrying out almost all executive calculations, as well as controlling impulses. It is said that when there are few molecules and they are degraded in the substantia nigra of the brain, that is when diseases such as Parkinson’s can appear and when there is an inadequate amount of dopamine in the prefrontal area, this can contribute to the appearance of schizophrenia and of psychosis. Over time, dopamine has been considered the center of pleasure, because it is the responsible for regulating motivation and desireas well as inducing those behaviors that have been positive and beneficial for the person in some way, to want to repeat them again.

Dopamine: functions

Among the main functions with which dopamine is related are the following:

  • Regulates memory. Adequate levels of dopamine in the prefrontal cortex increase short-term memory capacity. Whether dopamine levels increase exponentially or decrease, it will directly affect memory and, therefore, it will worsen.
  • Regulates movement. Adequate levels of dopamine in the brain regulate and control body movements. When there is a dopamine deficiency, the movements carried out by the person will be uncoordinated and will be slower. When there is an excess of dopamine levels, the body tends to make unnecessary movements, which is why tics usually appear repetitively. That is why it has an important relationship with the .
  • Reward and pleasure system. It is responsible for regulating pleasure in the brain through the . When we experience pleasant situations, the secretion of dopamine increases, so we increasingly seek out what is pleasurable and enjoyable.
  • Regulates attention. An optimal level of dopamine in the brain helps to considerably improve attention and concentration. On the contrary, when there is a low level of this neurotransmitter in the brain, this can influence the appearance of a disorder such as Attention Deficit Disorder (ADD).
  • Regulates sleep. It has been discovered that dopamine has a function in the pineal gland, which is responsible for regulating the circadian rhythm. The receptors of this neurotransmitter act by inhibiting the action of norepinephrine, regulating melatonin.
  • Cognition. Dopamine is responsible for controlling the flow of information in the frontal lobes of the brain. When there is a poor balance in dopamine levels in this area of ​​the brain, cognitive functions worsen.
  • Mood. Dopamine is related to people’s emotional well-being. An imbalance in the levels of this substance can lead to the appearance of some disorders such as depression, bipolar disorder, among others.
