The paper identifies conserved head direction circuits in bees, ants, and flies, showing stability over 300 million years with evolvable synaptic differences.

The paper compares brain region volumes across castes in two ant species to show how sensory demands shape neural architecture.

The paper presents a multi-resolution imaging and analysis pipeline for circuit reconstruction in insects, revealing conserved and specialized neural circuits across six species.

This study maps the central complex neuronal circuitry in bumblebees, identifying conserved and divergent features compared to fruit flies.

The paper describes a novel evolutionary structure of mushroom bodies in shore crabs, showing a departure from typical crustacean patterns with deep calyces and elaborate gyri.

The paper challenges the view that hemiellipsoid bodies are a derived crustacean trait and shows mushroom bodies exist in lineages predating Reptantia.
