Stone, T. et al. An anatomically constrained model for path integration in the bee brain. Curr. Biol. 27, 3069–3085.e11 (2017). It doesn’t have to be that way. In this article we will introduce you to the main concepts of neuroanatomy and the major structures of the nervous system. After that, you can dive into our series of easy-to-read study materials, so that at the end of your neuroanatomy journey you’ll feel more like Frodo Baggins, rather than the fallen Boromir. Key facts about neuroanatomy Nervous system Some of the best questions are from young scientists. Take for example this question about butterfly brains from a 5th grade student. Greer asked if a butterfly's brain is the same as when it was a caterpillar. Now that is a fantastic question. Scientists think that studying their brains can help us understand how the brain is involved in speciation, or the formation of distinct species through evolution.The researchers think that these subtle differences in brain structures help keep the two butterfly lineages apart, contributing to their being two different species. It’s likely that the differences in brain structure impacts behavior such as foraging or mating, leading to divergent behaviors. Heinze, S. Unraveling the neural basis of insect navigation. Curr. Opin. Insect Sci. 24, 58–67 (2017).

Brain tumours are also called primary (which start in the brain) and secondary (which spread to the brain). Nguyen, T. A. T., Beetz, M. J., Merlin, C. & el Jundi, B. Sun compass neurons are tuned to migratory orientation in monarch butterflies. Proc. Biol. Sci. 288, 20202988 (2021). Get started with central nervous system anatomy and the development of the central nervous system. Cerebrum and cerebral cortexDo butterflies have brains? Yes, like other life forms, the butterfly brain is its control center and sends and receives signals throughout the body. Butterflies start off as eggs, develop into caterpillars, and undergo metamorphosis to become butterflies. During this transformation, most parts of the caterpillar's body, including muscle and other cells, are broken down and rebuilt. However, the caterpillar brain cells are reused and adapt to control the butterfly's new parts. Hulse, B. K. et al. A connectome of the Drosophila central complex reveals network motifs suitable for flexible navigation and context-dependent action selection. Elife 10, 66039 (2021).
