Brainacle enables interactive delineation and quantification of anatomical structures in 3D data using virtual reality, validated on brain regions of African cichlid fish.

The study compares two populations of Neolamprologus brevis cichlids, finding that higher social interaction frequency correlates with larger brain size and specific neuroanatomical changes.

This study compares brain size and architecture across ten cichlid species in different habitat complexities, finding larger brains in less complex habitats, challenging the Clever Foraging Hypothesis.
