Feedback mechanisms are pervasive across the nervous system, regulating neural networks through the backpropagation of information at different levels. Neuroanatomical data have shown the presence of feedback neurons within the visual system of $\textit{Drosophila}$, where information such as visual motion is extracted. However, prevailing models of motion detection, as well as other visual features, rely on feedforward networks, so far neglecting feedback adjustments originating from higher hierarchical levels. The functional significance of feedback circuits, particularly inhibitory feedback
