While research in previous decades demonstrated a link between the pulvinar nucleus of the thalamus and visual selective attention, the pulvinar's specific functional role has remained elusive. However, methodological advances in electrophysiological recordings in non-human primates, including simultaneous recordings in multiple brain regions, have recently begun to reveal the pulvinar's functional contributions to selective attention. These new findings suggest that the pulvinar is critical for the efficient transmission of sensory information within and between cortical regions, both synchronizing cortical activity across brain regions and controlling cortical excitability. These new findings further suggest that the pulvinar's influence on cortical processing is embedded in a dynamic selection process that balances sensory and motor functions within the large-scale network that directs selective attention.

灵长类动物注意力网络中的动态 pulvino-cortical 相互作用。

虽然过去几十年的研究表明丘脑的枕骨核与视觉选择性注意之间存在联系,但枕骨的特定功能作用仍然难以捉摸。然而,非人类灵长类动物电生理记录的方法学进步,包括同时记录多个大脑区域,最近开始揭示 pulvinar 对选择性注意的功能贡献。这些新发现表明,脑室对于皮层区域内和皮层区域之间有效传递感觉信息至关重要,既可以同步跨大脑区域的皮层活动,又可以控制皮层兴奋性。这些新发现进一步表明 pulvinar'
