  "account": "Insects demonstrate impressive behavioral capabilities using limited neural resources, optimized for their unique environments. To fully comprehend or recreate these behaviors, researchers must consider the complex interactions between the environment, the insect's sensory periphery, and its internal biophysical processes. RhabdoForge, a versatile rendering framework, tackles these challenges for insect neuroethology and neuromorphic research. Compatible with Python workflows, this modular system supports both real-time ray-tracing and stochastic path-tracing via hardware-agnostic GPU pipelines.\n\nUnlike traditional models that treat each ommatidia as a pixel, RhabdoForge offers a highly customizable approach. Each layer of the compound eye - from its geometric structure and topological arrangement to the internal rhabdomere design - can be independently manipulated. This enables researchers to explore high-frequency, sub-ommatidial rhabdomere photomechanical actuation, revealing active sensing mechanisms within real-time, closed-loop environments. Additionally, the automated morphological pipeline converts 2D anatomical data into precise 3D sensory models.\n\nThe framework's effectiveness is demonstrated through two case studies. One involves optimizing optic-flow centering in a virtual tunnel, while the other recovers spatial hyperacuity through rhabdomere microsaccades. By bridging high-fidelity visual ecology and neuromorphic modeling, RhabdoForge empowers researchers to investigate how sensory optics and neural processing collaborate to generate intricate behavior in both biological and artificial agents.",
  "summary": "Insects solve complex behavioural tasks with remarkable efficiency, using minimal neural hardware tuned to the specific requirements of their ecological niches. To truly understand or replicate these behaviours, it is insufficient to model the brain in isolation: one must account for the dynamic, closed-loop interactions between the environment, the physical organisation of the sensory periphery,…",
