Sammanfattning : The evolution of the vertebrate brain has remained a topic of intense interest from biologists over many decades. Evolutionary biologists have seen it as an intriguing example of how the size and structure of a trait evolves across large phylogenies and under body size constraints, with both large shifts in deep evolutionary time and continuous smaller scale adaptation.

2. Brain morphology and behaviour in the guppy (Poecilia reticulata) : Effects of plasticity and mosaic brain evolution
Sammanfattning : Understanding how brains have evolved and subsequently culminated in the huge variation in brain morphology among contemporary vertebrate species has fascinated researchers for many decades. It has been recognized that brain morphology is both genetically and environmentally determined. LÄS MER
Sammanfattning : Many disorders are associated with regional brain volumes. The analysis of these volumes from MR images often requires sequential processing steps such as localization and delineation. LÄS MER
Sammanfattning : Brain size varies greatly among vertebrates. It has been proposed that the diversity of brain size is produced and maintained through a balance of adaptations to different types and levels of cognitive ability and constraints for adaptive evolution. LÄS MER
5. High-resolution Studies of mRNA Expression in Brain : A Search for Genes Differently Expressed in Schizophrenia
Sammanfattning : Gene expression differences between patients and controls can be used to find susceptibility genes and drug targets for a disease. High-resolution strategies are required because the differences between the investigated groups may be small and numerous factors may affect the mRNA quantity. LÄS MER
