Integrating brain, behavior, and phylogeny to understand the evolution of sensory systems in birds

摘要: The comparative anatomy of sensory systems has played a major role in developing theories and principles central to evolutionary neuroscience. This includes the tenet many studies, principle proper mass, which states that size neural structure reflects its processing capacity. structures within system is not, however, only salient variable evolution. Further, evolution brain behaviour are intimately tied phylogenetic history, requiring studies integrate neuroanatomy with phylogeny gain more holistic view Birds have proven be useful group for these because widespread interest their relationships wealth information on functional organization most pathways. In this review, we examine mass relation differences capabilities among birds. We discuss how neuroanatomy, can integrated understand birds providing evidence from visual, auditory somatosensory systems. also consider concept “trade-off”, whereby one (or subpathway system), may expanded size, at expense others, reduced size.
