Navigation often occurs under uncertain conditions, where spatial
information is incomplete. In this thesis project, we set out to study
how uncertainty affects the head direction (HD) system in the
_Drosophila_ brain, a biological ring attractor where a "bump" of
activity tracks the animal's HD as it moves around. We found that the
shape of this bump of activity reflects the uncertainty of the
environment, and correlates with adaptive remapping of the heading
representation. Specifically, the bump becomes wider in uncertain
conditions where HD encoding is unstable. Notably, individuals with
wider bumps are better able to learn a dramatic remapping of the HD
representation when the environment changes. We found that an
environment with multiple sensory cues improves HD encoding and
decreases bump width. In a multi-cue environment, different individuals
assign different levels of uncertainty to different cues, and this
predicts the relative weight that they will assign to each cue during
cue conflict. Together, these results show how uncertainty can alter the
format of a spatial map to produce adaptive changes in cue integration
and learning.
