Filter by:The oral comprehension (OC) of a second language (L2) involves different cognitive processes, specially during the learning phase. This study aims at investigating the neurophysiological functioning of different steps involved in this oral understanding.
Language is a signature human cognitive skill, but the precise computations that support language understanding remain unknown. This study aims to combine high-quality human neural data obtained through intracranial recordings with advances in computational modeling of human cognition to shed light on the construction and understanding of speech.
Delayed discharge in geriatric units is a health and economic issue. There is no algorithm to automatically measure the appropriateness of admissions or hospital days. 30% of the days of hospitalization in acute geriatric units (AGU) are not appropriate. Waiting for a transfer to a follow-up care and rehabilitation unit (SSR) is the main risk factor for inappropriate days. The purpose of this project is to develop an algorithm using natural language processing to predict the appropriateness of an admission to UGA, or a day at UGA.
At present, functional imaging studies have suggested that the Geschwind's territory (the inferior parietal lobe) is an important language area. It is the hub for semantics and phonetic language processing. However, the type and mechanism of aphasia after injury of Geschwind's territory and the subsequent recovery of language are still unclear. In our study based on brain injury model of brain arteriovenous malformation (BAVMs) resection, investigators found that the incidence of aphasia was higher after the injury of Geschwind's territory than after injury of the classical language area, and the type of aphasia was complicated, while the recovery rate of language disorder was high during follow-up. Investigators hypothesized that the type of aphasia may be associated with the type of brain connectivity damaged, and that reorganization of brain connections and brain network promote the recovery of language function. In this study, we aim to investigate the types of aphasia and their corresponding brain network changes after the resection of BAVMs located in the Geschwind's territory. Investigators will evaluate language function and collect multimodality images of the patients before resection of the lesions, as well as 7 days, 3 months and 6 months afterwards. In addition, the anatomical brain connectivity and brain network will also be analyzed. Our research will not only be a meaningful exploration for mechanisms of human language function damage and reorganization, but will also provide an important basis for the protection of brain function in neurosurgery.
