This study attempted to identify the vestibular cortex that is involved in the perception of vestibular vertigo in the human brain. We used single-photon emission computed tomography (SPECT) to measure regional cerebral blood flow (rCBF) in two cerebrovascular patients with nystagmus-sensation dissociation, which is known as brisk caloric nystagmus without simultaneous sensation of vertigo. Both patients had ischemic lesions involving mainly the parieto-temporal lobe in the nondominant hemisphere. It is suggested that the parieto-temporal lobe in the nondominant hemisphere contains the vestibular cortex which is a center for the perception of vertigo due to vestibular stimulation.
本研究试图确定人类大脑中参与前庭性眩晕感知的前庭皮层。我们使用单光子发射计算机断层扫描（SPECT）来测量两名患有眼球震颤感觉分离（即冷热试验时出现明显眼球震颤但无同时眩晕感）的脑血管疾病患者的局部脑血流量（rCBF）。两名患者均有主要累及非优势半球颞顶叶的缺血性病变。提示非优势半球的颞顶叶包含前庭皮层，它是前庭刺激所致眩晕感知的中枢。
