许多认知神经科学的研究人员和临床医生坚持认知功能的模块化观点,即大脑皮层通过激活具有有限基本认知功能的区域来运作。然而,正在进行的向动态网络视角的范式转变正在进行中。这一新的观点认为,皮质功能源于皮质区域内部和之间的协调动力学。大脑皮层协调动力学的产生是由于来自投射到大脑皮层的其他区域的输入对大脑皮层区域施加的单向影响,以及以大脑皮层连通性为特征的投影互易性,并引起折返处理。因此,大脑皮层动力学表现出分离和整合的趋势,并在大脑皮层内和大脑皮层区域之间产生合作和竞争关系,这些关系被认为是大脑中认知出现的基础。
Many researchers and clinicians in cognitive neuroscience hold to a modular view of cognitive function in which the cerebral cortex operates by the activation of areas with circumscribed elementary cognitive functions. Yet an ongoing paradigm shift to a dynamic network perspective is underway. This new viewpoint treats cortical function as arising from the coordination dynamics within and between cortical regions. Cortical coordination dynamics arises due to the unidirectional influences imposed on a cortical area by inputs from other areas that project to it, combined with the projection reciprocity that characterizes cortical connectivity and gives rise to reentrant processing. As a result, cortical dynamics exhibits both segregative and integrative tendencies and gives rise to both cooperative and competitive relations within and between cortical areas that are hypothesized to underlie the emergence of cognition in brains.
