The Cambridge Science Festival was a thoroughly exciting experience in which we got to combine our multi-disciplinary interests and communicate those interests to many people ranging from the young to old. For the festival, I created kid-friendly foam bookmarks with the molecular structure of Dopamine and a quick summary or outline of the function of Dopamine as a hormone. Specifically, I looked into Dopamine as a prolactin-inhibiting factor. Within the hypothalamus, the release of dopamine inhibits prolactin secretion. The dopamine produced by neurons is secreted into certain blood vessels, which supply the pituitary gland. The dopamine thus inhibits secretion of the prolactin in the lactotrope cells that produce the prolactin, which is the hormone linked to the release of breast milk during and after pregnancy. I chose to focus on this function of dopamine as a prolactin-inhibiting hormone in order to give a different view of the functions of dopamine. From previous psychology knowledge, I often hear dopamine as related to pleasure, gratification, and happiness. What I did not know, however, was that dopamine is also related to regulation of the release of milk in breast-feeding, which I think of as an important function that many people may not know about. This unanticipated function of dopamine actually surprised many people today, including a visiting student from the University of Pennsylvania who is very familiar with neurotransmitters. What I did find difficult, however, was relating this information to little children. Given the kid-friendly atmosphere, I did not think that it was appropriate to delve into the topic of lactation with children. Thus, Aisha and I focused more on dopamine’s function in terms of diseases, reward-motivated behavior, and cognition. Overall, I was quite pleased with our presentation to the public and I hope the Ruhlman presentation is even more cohesive and coherent.
