This paper identifies a fossilized brain in the trilobite Yunnanocephalus yunnanensis, revealing a bilaterally organized cerebrum with domains typical of euarthropod brain organization.

The paper describes the brain organization of Xandarella spectaculum, showing modifications from the ancestral cerebral ground pattern that may have contributed to its extinction.

This paper describes the neural anatomy of Jianfengia multisegmentalis, a Cambrian stem euarthropod, and shows its similarities to modern Pancrustacea.

The paper identifies neuronal tissue structures in Mollisonia symmetrica that reveal a neuroanatomical organization distinct from merostomes, suggesting a marine origin for arachnids.

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 identifies conserved gene regulatory networks specifying midbrain circuitry in arthropods and vertebrates, showing functional parallels between Drosophila DTB and vertebrate MHB.

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

The paper identifies a lineage-related reciprocal inhibition circuit in Drosophila that mediates sensory-motor action selection through competitive inhibition.
