Throughout history, vestibular and emotional dysregulation have often manifested together in clinical settings, with little consideration that they may have a common basis. Regarding vestibular mechanisms, the role of brainstem and cerebellar structures has been emphasized in the neurological literature, whereas emotion processing in the cerebral hemispheres has been the focus in psychology. A conceptual model is proposed that links research in the 2 disparate fields by means of a functional cerebral systems framework. The claim is that frontal regions exert regulatory control over posterior systems for sensation and autonomic functions in a dense, interconnected network. Impairment at levels within the system is expected to influence vestibular and cognitive processes depending on the extent of frontal regulatory capacity. M. Kinsbourne's (1980) shared cerebral space model specifies the conditions under which dysfunction of the vestibular modality will influence higher cognitive levels. A position on laterality and associative relations within the right hemisphere is proposed to explain links among dizziness, nausea, and negative emotion.
纵观历史，前庭功能失调和情绪调节障碍在临床环境中常常同时出现，但人们很少考虑它们可能有共同的基础。关于前庭机制，神经学文献强调了脑干和小脑结构的作用，而心理学则聚焦于大脑半球的情绪处理。本文提出了一个概念模型，通过功能性脑系统框架将这两个不同领域的研究联系起来。该模型认为，额叶区域在一个密集的、相互连接的网络中对后系统的感觉和自主功能施加调节控制。预计系统内各水平的损伤将根据额叶调节能力的程度影响前庭和认知过程。M. 金斯伯恩（1980年）的共享脑空间模型明确了前庭模式功能障碍影响更高认知水平的条件。本文提出了关于右半球内偏侧性和联想关系的一种观点，以解释头晕、恶心和负面情绪之间的联系。
