Numerous analogies can be found for the human brain. It is sometimes compared to a computer where different operations are compartmentalized to certain parts that are wired together. Other specialists describe the mind as a group of roads and highways based on the continual signal traffic that shoots back and forth between the neurons and the remainder of the body. When getting caught in the grips of addiction, one needs to be these views of the brain in mind. Illegal substances, prescribed drugs and the tremendous effect both categories have on behavior may also be tracked to specific pathways and parts of the brain.
It is critical to know the main constituents involved, in order to give a more detailed understanding of how addiction affects the brain. The primary components are the neurotransmitters, the acting neurological and chemical substances. Different brain cells or neurons can communicate with each other though these transmitting particles and combined, they create all of the brain’s circuitry. With respect to drug dependency, only specific neurotransmitters are related to the benefits of substance use.
The main neurotransmitter that is directly involved in reward is dopamine. The natural discharge and acceptance of this part of the brain brings about pleasure and other emotional regulations.Serotonin is another essential neurotransmitter that has many functions within the human mind, inclusive of the regulation of body temperature, sleep patterns, mood, appetite and pain processes. How most drugs administered by clinician’s works is by increasing the level of serotonin in the brain. Finally, glutamate and gamma-aminobutyric acid (GABA) are other major transmitters of the brain that manage restrictive and simulative body responses.
The other aspect to look at is the different centers of the brain that communicate through these paths as well as the neurotransmitters that pass through them. With dopamine, there are three distinctive paths involved in the sending of the desirable neurochemical. The path that is primarily responsible for motor control is comprised of the substantial nigra and the striatum. A collection of locations known as the ventral tegmental area that are linked to the nucleus accumbens, amygdala, hippocampus and prefrontal cortex make up the mesolimbic and mesocortical pathways. This network is most importantly involved with the reinforcement of addictive behaviors but is also involved with memory, motivation and emotion. The tuber infundibular pathway, which joins the hypothalamus to the pituitary gland, is the third dopamine pathway. This critical connection affects how hormones are regulated, behaviors associated with different hormones as well as a variety of senses.
In a nutshell, neurotransmitter structures are intertwined. The raphe nuclei, which discharges and propels the substance to the furthest areas of the brain and the spinal cord are the parts of the brain that are involved in producing serotonin. Glutamate and GABA can be found all over the brain too. Even though Illegal drugs often affect dissimilar areas of the brain’s reward system, they still share in the increase of the same neurotransmitters. This is so because the drugs often more than one paths and attain high levels of euphoria. Each of these, dopamine, serotonin or GABA, are affected in hazardous and simultaneous ways during a severe addiction.
With so many areas of the brain being radically plagued by drug use and consequent addiction, we can see how person’s thoughts, emotions and behaviors can be easily impacted and why it is vital treat the addiction before it gets out of hand.Back to Blog
