Study Notes
Brain Reward Pathway
- The primary function of the brain reward pathway is to respond to rewarding stimuli and anticipate reward.
Neural Connections
- The ventral tegmental area (VTA) connects the nucleus accumbens and the prefrontal cortex through dopamine-containing neurons.
Neurotransmitters
- The VTA releases dopamine in response to primary rewarding stimuli and in anticipation of reward.
Reward Pathway Characteristics
- A distinguishing feature of the reward pathway compared to the substantia nigra-striatal pathway is the release of dopamine in response to reward anticipation.
Addiction
- A common characteristic of addiction is the dysregulation of the brain reward pathway, leading to persistent seeking of reward despite negative consequences.
