Over the past few years, the neural bases of mental imagery have been both a topic of intense debate and a domain of extensive investigations using either PET or fMRI that have provided new insights into the cortical anatomy of this cognitive function. Several studies have in fact demonstrated that there exist types of mental imagery that do not rely on primary/early visual areas, whereas a consensus now exists on the validity of the dorsal/ventral-route model in the imagery domain. More importantly, these studies have provided evidence that, in addition to higher order visual areas, mental imagery shares common brain areas with other major cognitive functions, such as language, memory, and movement, depending on the nature of the imagery task. This body of recent results indicates that there is no unique mental imagery cortical network; rather, it reflects the high degree of interaction between mental imagery and other cognitive functions.
在过去几年里，心理意象的神经基础一直是激烈辩论的话题，也是使用正电子发射断层扫描（PET）或功能磁共振成像（fMRI）进行广泛研究的领域，这些研究为这种认知功能的皮质解剖学提供了新的见解。事实上，多项研究表明，存在不依赖于初级/早期视觉区域的心理意象类型，而目前对于背侧/腹侧通路模型在意象领域的有效性已达成共识。更重要的是，这些研究提供了证据，表明除了高阶视觉区域外，根据意象任务的性质，心理意象与其他主要认知功能（如语言、记忆和运动）共享共同的脑区。最近的这一系列研究结果表明，不存在独特的心理意象皮质网络；相反，它反映了心理意象与其他认知功能之间的高度相互作用。
