基础前脑通过处理奖励信号来影响注意力. 加强BF和前皮层 (PrL) 之间的连接对于准确,有动机的注意力至关重要.
科学领域:
- 神经科学是一个神经科学.
- 认知神经科学 认知神经科学
- 计算神经科学是一种神经科学.
背景情况:
- 基础前脑 (BF) 在注意力方面发挥着关键作用,特别是在响应与奖励相关的刺激时.
- BF参与编码动机突出,并准备注意力处理的前额回路.
研究的目的:
- 为了研究前皮质 (PrL) 和BF之间的功能连接.
- 了解这种连接如何根据奖励线索调节注意力.
主要方法:
- 在PrL和BF记录的本地现场潜力 (LFPs).
- 在涉及奖励线索的注意力任务中分析了theta和gamma功率和连贯性.
- 评估了BF和PrL之间的信息流的方向性.
主要成果:
- 和马功率与行为表现有很强的相关性.
- 在错误的响应过程中,观察到两个频段的功率较低.
- 从BF到PrL增加的连贯性和单向信息流与正确的响应有关.
结论:
- 在高度激励的注意力资源招募过程中,BF和PrL之间的连接性得到加强.
- 这种增强的连接对于准确,以奖励为导向的注意力至关重要.
