Learn about the mechanism of dopamine and what happens in the brain when it is flooded with dopamine. How do methamphetamine, cocaine, and amphetamine affect the neurotransmitters and dopamine released in the brain? What is the fine line between psychosis and normative brain? Explore what goes in the brain when it is overloaded with dopamine and how this affects the brain’s garbage collector cells (microglia), which in turn causes oxidative stress and an increase in free radicals in the brain. What is the outcome of repeated dopamine overload in the brain, and how does this affect neuroplasticity?
