摘要: 大脑具有可塑性,神经反馈训练有助于大脑神经损伤康复。由于药物治疗存在耐药性等副作用,基于神经反馈的大脑康复训练是当前的研究热点。大脑调控是临床大脑疾病如孤独症和多动症的有效治疗手段,其主要通过高级认知任务训练逐步恢复大脑认知功能。认知任务训练形式多样,文中引入Unity3D游戏引擎,设计并开发了一种神经反馈治疗系统——极速赛车(Speeding)。首先,本系统在传统思维训练的基础上引入了神经反馈机制。每隔一段时间对玩家的游戏数据进行检测,根据检测情况及时调整训练难度,增强训练目的性和针对性,提高训练效率。其次,本系统引入了多任务训练机制,利用地图和宝石道具开展多任务思维训练,使玩家的注意力更加集中,提高训练的效果。通过设计不同难度的场景对应梯度阈值,引入延迟检测函数模块实时调整思维训练难度。本系统将为有效改善大脑工作状态,实现大脑神经系统康复和治疗提供技术支持。
