There has been a recent and dramatic growth of interest in the psychological and neural mechanisms of multisensory integration between different sensory modalities. Much of this recent research has focused specifically on how multisensory representations of body parts and of the 'peripersonal' space immediately around them, are constructed. Research has also focused on how this may lead to multisensorially determined perceptions of body parts, to action execution, and even to attributions of agency and self-ownership for the body parts in question. Converging evidence from animal and human studies suggests that the primate brain constructs various body-part-centred representations of space, based on the integration of visual, tactile and proprioceptive information. These representations can plastically change following active tool-use that extends reachable space and also modifies the representation of peripersonal space. These new results indicate that a modern cognitive neuroscience approach to the classical concept of the 'body schema' may now be within reach.
最近,人们对不同感觉模态之间多感官整合的心理和神经机制的兴趣急剧增长。近期的许多研究特别关注身体部位及其周围“个人周边”空间的多感官表征是如何构建的。研究还聚焦于这如何导致对身体部位的多感官决定的感知、动作执行,甚至对相关身体部位的能动性和自我所有权的归属。来自动物和人类研究的越来越多的证据表明,灵长类动物的大脑基于视觉、触觉和本体感觉信息的整合,构建了各种以身体部位为中心的空间表征。这些表征会随着主动使用工具而发生可塑性变化,主动使用工具会扩展可触及空间,也会改变个人周边空间的表征。这些新结果表明,现在可能可以用现代认知神经科学方法来研究“身体图式”这一经典概念了。
