# brain: the flexible mental maps of flies

<< In the Drosophila brain, 'compass'  neurons track the orientation of the body and head (the fly’s heading) during navigation >>

<<  a visual cue can evoke synaptic inhibition in compass neurons and that R (ring) neurons mediate this inhibition. Each compass neuron is inhibited only by specific visual cue positions, indicating that many potential connections from R neurons onto compass neurons are actually weak or silent. (..) the pattern of visually evoked inhibition can reorganize over minutes as the fly explores an altered virtual-reality environment. >>
