概括

新的研究揭示了大脑如何控制视觉空间注意力,当个人做出自己的选择. 这项研究突出了涉及"自愿注意"的前对对决策网络,与外部引导的注意力不同.

科学领域:

认知神经科学认知神经科学
神经成像是一种神经成像.
视觉注意力视觉注意力

背景情况:

暗示范式是研究视觉空间注意力的标准.
意愿的注意力涉及到对空间焦点的自发决定,与受指示的注意力形成对比.

研究的目的:

为了研究潜在的神经机制,自愿的注意力控制.
为了比较指导与意愿注意期间的大脑活动.

主要方法:

从两个机构 (美国联邦大学和加州大学戴维斯分校) 分析了fMRI和EEG数据.
利用了一种新的意愿关注范式.
检查了大脑网络激活和EEG振荡模式.

主要成果:

指示和选择线索都激活了背部注意网络 (DAN).
此外,选择线索还参与了前端对象决策网络 (dACC,AI,APFC,DLPFC,IPL).
意愿注意的决定可以在前端对象网络中解码;EEGα振荡预测了注意的方向.

结论:

预期的注意力涉及一个独特的前对对决策网络.
神经活动模式区分受指示的注意力和自我决定的注意力.
基于这些发现,提出了自愿注意力控制的模型.

High-Level and Low-Level Awareness

Controlled processes in human consciousness represent high-alert mental states where individuals deliberately focus their attention on achieving specific goals. Controlled processes can be seen in situations like mastering new technology, where a person might become so absorbed that they ignore surrounding distractions. Such processes involve selective attention, requiring one to concentrate on particular elements of experience while disregarding others. These are governed by executive...
