 The study found that the nucleus accumbens, NAC, is influenced by colonergic interneuron, CIN, activity when it comes to motivational processes. This CIN activity was shown to control the release of dopamine, DA, from the NAC core, which is critical for motivation. Additionally, the study found that CIN activity could also affect motivation through the release of DA, which is important for reward-based decision making. Furthermore, the study demonstrated that CIN activity could be used to manipulate motivation in animals, suggesting that it may play a role in human motivation as well.
