Study Notes
- The Ventral Tegmental Area (VTA) in the brainstem releases dopamine, a neurotransmitter, in response to pleasurable stimuli
- The dopamine released travels to various parts of the brain, including the nucleus accumbens, amygdala, and hippocampus, through the mesolimbic pathway
- The nucleus accumbens helps control motor functions and encourages repeated pleasurable behavior
- The amygdala processes emotions and helps remember the context of pleasurable experiences
- The hippocampus is responsible for forming memories and helps recall details of pleasurable experiences
- The release of dopamine and activation of the reward pathway can lead to feelings of happiness or euphoria
- Prolonged activation of the reward pathway can lead to decreased levels of serotonin, a neurotransmitter responsible for feelings of satiation, making it harder to feel satisfied and increasing the risk of addiction.
