| Outline of Final Research Achievements |
Although the neural substrate underlying automatic detection of one’s own body instability is an important consideration, there have ever been few functional neuroimaging studies due to the restrictions placed on participants’ movements. Here, we used fMRI to investigate the neural substrate underlying whole body instability based on a self-recognition paradigm. Analyses revealed significant activity in the brain regions that should be activated during genuine unstable body (physical) conditions: the right parieto-insular vestibular cortex, inferior frontal junction, posterior insula and parabrachial nucleus. We argue that these right-lateralized cortical and brainstem regions mediate vestibular information processing for detection of vestibular anomalies, defensive motor responding in which the necessary motor responses are automatically prepared/simulated to protect one’s body, and sympathetic activity as an alarm response during whole body instability.
