New paper helps unravel the mysteries behind brain diversity
Morphogenesis underlying the development of the everted teleost telencephalon.
Monica Folgeira, Steve Wilson and John Clarke
Brain diversity has puzzled scientists for centuries. But, what do we mean by “brain diversity”? If one compares brains from many different species of vertebrates, soon one realizes how different they look. This diversity in brain form or morphology is extraordinary not only for brains from very separate groups (e. g. mammals vs. fishes), but also within the same group.
Take as an example “ray-finned fishes”, a group of fishes with more than 30,000 species and whose members have fins supported by bony spines. Within this group, brain morphology can be very different even between closely related species. In order to understand how brain diversity is generated, we studied in detail the development of the telencephalon of the zebrafish (a ray-finned fish).
