神经科学在历史上利用了多种多样的动物类群。然而,最近的研究越来越多地集中在一些模式物种上。这一趋势随着基因革命而加速,因为基因组序列和遗传工具可用于少数物种,这形成了瓶颈。这种在一小部分模型物种上的结合带来了一些通常没有考虑到的成本,特别是在目前明确使用小鼠作为人类疾病模型的情况下。战略选择的非模式物种的比较研究可以补充模式物种的研究,并产生更严格的研究。随着基因序列和工具可用于更多物种,我们有望摆脱瓶颈,再次利用比较研究提供的丰富生物多样性。
Neuroscience historically exploited a wide diversity of animal taxa. Recently, however, research focused increasingly on a few model species. This trend accelerated with the genetic revolution, as genomic sequences and genetic tools became available for a few species, which formed a bottleneck. This coalescence on a small set of model species comes with several costs often not considered, especially in the current drive to use mice explicitly as models for human diseases. Comparative studies of strategically chosen non-model species can complement model species research and yield more rigorous studies. As genetic sequences and tools become available for many more species, we are poised to emerge from the bottleneck and once again exploit the rich biological diversity offered by comparative studies.
