To navigate in a natural environment, a flying fly must estimate and contend with external forces such as wind. Estimating wind direction is difficult because the fly cannot directly sense ambient wind in flight. Instead, the fly experiences a vector sum of self-generated motion and the motion imposed by wind, which produces both mechanosensory (airflow) and visual (optic flow) experience. How the fly brain integrates these sensory inputs to estimate ambient wind direction is not known. Here we explore how a circuit in the Drosophila Central Complex (CX) might integrate airflow and optic flow
