Beyond the Hype: Closing the Loop in Drosophila Connectomics

Recent excitement around connectome-based simulations in Drosophila is valuable, but the core scientific challenge is deeper than hype. The key is to close the loop between neural structure, dynamics, embodiment, and sensory feedback.

Nature 2024 (Shiu et al.) highlights central-brain sensorimotor transformations in specific circuits, while NeuroMechFly v2 pushes embodied mechanics and feedback further. These are major steps, but they do not yet solve the full problem of whole-animal behavior emerging from coupled brain, ventral nerve cord (VNC), and motor circuits.

My current work sits in that intersection, with focus on Drosophila CNS, especially VNC and foreleg-related motor circuits, where descending drive, premotor organization, proprioception, and body mechanics meet directly.

We are still far from fully emulating a fly in silico, but we are moving toward something scientifically stronger: understanding, step by step, how connectome structure becomes action, coordination, and behavior.
