Neuroregulatory Effects of Microcone Patch Stimulation on the Auricular Branch of the Vagus Nerve and the Prefrontal Cortex: A Feasibility Study.

: The primary purpose of this study was to preliminarily examine the effects of autonomic nervous system activity on the dorsolateral prefrontal cortex. Recent studies have examined approaches to modulating autonomic activity using invasive and non-invasive methods, but the effects of changes in autonomic activity during cognitive tasks on the dorsolateral prefrontal cortex have not been fully investigated. The purpose of this preliminary investigation was to examine changes in autonomic activity and blood oxygen saturation in the dorsolateral prefrontal cortex during reading tasks induced by vagus nerve stimulation using a microcone patch.

[A Trial of Unified Management of Language Tasks Using a Tablet Device for Language Area Mapping].

Language tasks must be based on perioperative neuropsychological evaluation during intraoperative language area mapping for the resection of brain tumor near the language cortex under awake craniotomy. However, flexibility is needed during surgery, because actions during surgery must change based on neurological symptoms and the presence or absence of aphasia. Here, we developed software to assess patients' ability to complete language tasks during surgery by using a tablet device; these language tasks serve as indicators of changes in patient status.
