In this episode, Brandon Couch explores the neurobiology of addiction, detailing how psychoactive drugs affect the brain and nervous system. He explains the structure and function of the nervous system, the role of neurons and neurotransmitters in communication, and how various drugs interact with these systems to produce their effects. The conversation emphasizes the importance of understanding these biological processes in the context of addiction and recovery. Takeaways

• Psychoactive drugs affect the brain by altering neurotransmission.
• The nervous system is crucial for understanding addiction.
• Neurons transmit electrical messages throughout the body.
• The synapse is where neurotransmitters interact with receptors.
• Depressants and stimulants have opposing effects on neurotransmission.
• Neurotransmitters like dopamine and serotonin play key roles in mood and behavior.
• Drugs can mimic or block natural neurotransmitters at their receptors.
• Understanding the nervous system aids in recovery from addiction.
• Chemical transmission is essential for neuron communication.
• Knowledge of neurobiology can empower recovery efforts.
