Neurobiological Components of Addiction: Understanding the Reward Pathway

 Neurobiological Components of

Addiction: Understanding the Reward

Pathway

Reward pathway

The basic concept in the neurobiology of addiction is the reward pathway which comprises the areas of the brain most involved in addiction. 

The limbic system

Home of the areas of the brain thought to make up the reward pathway. When stimuli activate particular areas of the brain then pleasurable sensations are produced. Neurotransmitters play critical roles in transmitting information between neurons through synapses. A synapse measures twenty to fifty nanometers.

Dopamine

Dopamine is an important neurotransmitter involved in reward and euphoria experiences. Dopamine is made by very few brain cells and acts mainly within a subset of brain regions. Dopamine seems to have a disproportionately large impact on brain function.

Cocaine

Cocaine interferes with the normal action of dopamine by blocking the removal or reuptake of dopamine which results in an increase of dopamine in the neurons, resulting in overstimulation of receiving neurons called neuroreceptors. This is experienced by the user as a pleasurable euphoria. An addict seeks to continue experiencing this sensation which results from an abundance of powerful neurotransmitters including dopamine. In the brain, this dopaminergic transmission and reward pathway is a primary feature of addiction.

VTA

The VTA has emerged as a new research interest in understanding how addiction and drugs affect the brain. The stress of VTA may be a potential factor in relapse. Advanced research will unlock more keys to understanding the VTA and GABA's role in inhibiting or slowing the dopaminergic surge.

 Combating Negative Self-Talk

Negative self-talk is the inner voice that criticizes, doubts or belittles yourself. It can affect your mood, confidence, and performance at work. Negative self-talk can also lead to stress, anxiety, depression, and burnout. But how can you combat negative self-talk and replace it with positive affirmations? Here are some tips to help you:

• 
  Identify the triggers. What situations or events make you feel insecure, frustrated, or inadequate? Is it a difficult project, a demanding client, a challenging colleague, or a personal issue? Try to notice when and why you start to talk negatively to yourself. 
•  Challenge the thoughts. Don't accept your negative thoughts as facts. Ask yourself if they are realistic, helpful, or fair. For example, if you think "I'm not good enough for this job", ask yourself "What evidence do I have for this? How would I respond if a friend said this to me? What can I do to improve my skills or confidence?"
  
• Replace the thoughts. Once you have challenged your negative thoughts, replace them with positive ones. Use affirmations that are specific, realistic, and empowering. For example, instead of saying "I can't do this", say "I can do this if I work hard and ask for help when I need it".
• Practice gratitude. One way to combat negative self-talk is to focus on the positive aspects of your life and work. Make a habit of writing down or saying out loud three things you are grateful for every day. This can help you appreciate what you have and what you have achieved. 
•  Seek support. You don't have to deal with negative self-talk alone. Talk to someone you trust, such as a friend, family member, mentor, or therapist. They can help you gain perspective, offer encouragement, and provide feedback. You can also join a support group or online community where you can share your experiences and learn from others
