The fruit fly, Drosophila melanogaster, is a model organism that is widely used in neuroscience research. It has a small brain, which makes it easier to study than the brains of larger animals. Nevertheless, fruit flies’ brain architecture is able to form memories, learn, and engage in complex social behavior. Hence findings from studies in fruit flies' brains can often be applied to other animals, including humans.
A Connectome is a neuronal wiring diagram - map of all the connections between neurons in a brain. Having a full brain connectome of Drosophila is a valuable resource for neuroscientists. It enables studying the structure and function of the fruit fly brain in unprecedented detail, potentially leading to new insights into how the brain works and how it is affected by disease.
