albertcardona, "we illustrate that in our theory, the consistent presence of the eight-column organisation of head direction circuits across multiple insect species is not a chance artefact but instead can be explained by basic evolutionary principles."
Interesting take on possible constraints that defined the circuit architecture of the #Drosophila central complex in its role as a brain centre for spatial navigation.
