My paper on the head direction neurons in the larval zebrafish is now published on Nature! Read it here:
www.nature.com/articles/s41...The biggest update from the bioRxiv version is the reanalysis of the "double sun" experiment (heavily inspired by earlier fly works). Initially, we expected to see fish flip-flopping between (say) north- and south-facing interpretations in a scene with two-fold point symmetry.
Instead, fish seemed to remap 180º of the visual space onto the 360º extent of their neural compass, effectively "considering" the two suns as an identical object. This shows the surprising capacity of the HD cells to rapidly pick up the correlation structure of the visual inputs.
