This week's S.U.R.E participant is Callum Lorimer. Callum is working in the Neuromechanical Intelligence Laboratory (NeuroMINT) under Dr. Nicholas Szorcinski this summer, where he will be studying neural networks within Drosophila melanogaster, the common fruit fly, by integrating a synthetic nervous system with a computer model of the insect's frontal plane. He is programming the synthetic nervous system using the SNS-Toolbox python package, which allows users to add neurons and make connections between them to simulate the structure and function of biological nervous systems. MuJoCo physics simulation software, where body parts and muscle fibers based on the anatomy of Drosophila melanogaster, is being used to create a mechanical model of the fly. When both of these components are integrated, the result will be a neuromechanical model of a Drosophila melanogaster that will use sensory information from the physics simulation to adjust its motor output The input from the simulated model will include information about the fly's femur-tibia joint angle, movement speed, and direction, as well as information about the strain on the leg of the fly. This information will be processed by the synthetic nervous system, which will output instructions to the muscle fibers in the mechanical model, allowing it to maintain its posture and stabilize itself against unexpected external perturbations. This model can be applied to legged robots once complete, and ultimately will provide insight into how organisms integrate sensory information from multiple modalities to control their locomotion.
