Despite their small brain size, honeybees are able to orientate themselves exceptionally well in the environment. In order to study their navigational capabilities, correlations between brain activity of a bee and its visual perception are analysed. Neural activity of the animal was recorded while flying with a quadcopter. First, it is shown that similar brain activity was measured in repeated flight routes. Next, the flight of the copter is simulated in a virtual 3D environment of the experiment's fields and its surroundings. Images were rendered from the perspective of a bee and processed by an autoencoder. Activations of the encoder were correlated with the bee's neural activity. Additionally, the brain activity was projected onto a field in the range of a bee's field of view. Both approaches revealed high correlations during flight turns.
