区分大脑功能的“整体论”和“简化论”观点是很常见的，前者将大脑视为一个不可分割的单位，而后者则将大脑视为服务于不同功能的不同单位的集合。反对简化论的一些研究人员指出，皮质网络结构不尊重功能边界，神经解剖学家V.Braitenberg建议将大脑皮层理解为来自感觉输入、运动命令和内在产生的过程的神经元活动的“巨大混合机器”。在这篇文章中，我们提供了Braitenberg观点的上下文，并回顾了来自多个感觉输入的神经元活动与大脑皮层内固有神经元突起相互作用的证据。我们专注于从视听相互作用和呼吸对大脑功能的影响的研究中获得的新见解，这些似乎与区域功能边界的“简化论”观点不符。相反，它们表明功能边界是模糊的和上下文相关的。此外，我们讨论了感觉、本体感觉和内感信号对皮层活动的影响与理解脑-身体相互作用的相关性，强调了这些新见解对具身认知争论的一些结果，并对未来的研究提出了一些建议。
It is common to distinguish between “holist” and “reductionist” views of brain function, where the former envisions the brain as functioning as an indivisible unit and the latter as a collection of distinct units that serve different functions. Opposing reductionism, a number of researchers have pointed out that cortical network architecture does not respect functional boundaries, and the neuroanatomist V. Braitenberg proposed to understand the cerebral cortex as a “great mixing machine” of neuronal activity from sensory inputs, motor commands, and intrinsically generated processes. In this paper, we offer a contextualization of Braitenberg’s point, and we review evidence for the interactions of neuronal activity from multiple sensory inputs and intrinsic neuronal processes in the cerebral cortex. We focus on new insights from studies on audiovisual interactions and on the influence of respiration on brain functions, which do not seem to align well with “reductionist” views of areal functional boundaries. Instead, they indicate that functional boundaries are fuzzy and context dependent. In addition, we discuss the relevance of the influence of sensory, proprioceptive, and interoceptive signals on cortical activity for understanding brain-body interactions, highlight some of the consequences of these new insights for debates on embodied cognition, and offer some suggestions for future studies.
