fly's motion detection system in a specific way which in turn will have led to spe-
cific adaptations of the system analyzing it. Since present technology does not yet
allow to record from single neurons while the fly is free to fly around, present efforts
aim at recording the visual flow the fly is experiencing during free flight [82] which
can be later used as a stimulus presented to the tethered fly for electrophysiological
recording [62]. Along these lines, future modelling efforts that make use of neuro-
morphic chips implementing the fly motion detection circuits offer the advantage to
be testable in closed-loop situations in real time (e.g., [65]).
