Article Synopsis
- Dopamine neurons in the ventral tegmental area play a key role in intracranial self-stimulation (ICSS), but their exact cognitive functions are still not fully understood.
- 20-Hz stimulation of dopamine neurons mimics a weak prediction error and fails to support ICSS beyond a simple reinforcement schedule, lacking the ability to assign value to cues.
- In contrast, 50-Hz stimulation significantly enhances ICSS, providing a specific reward representation that motivates behavior, indicating that the frequency of stimulation affects dopamine release modulations.
