这篇博客介绍了大脑的注意力网络，包括背侧注意力网络(DAN)、腹侧注意力网络(VAN)和外部注意力系统(EAS)，详细阐述了它们的功能和相关脑区。DAN负责选择性注意力，VAN则处理自下而上的注意力过程，EAS通过两者的灵活交互实现动态注意力控制。此外，还提到了前额皮层-顶叶网络和扣带回-脑回网络在认知控制和维持工作记忆中的作用。

Dorsal Attention Network

pDLPFC / frontal eye fields
Posterior parietal cortex: Superior parietal lobule (SPL) / Intra-parietal sulcus (IPS)
rITC (above FPN region)

Functions: Selective attention.

Ventral Attention Network (VAN)

Ventro-lateral prefrontal cortex – middle frontal gyrus (MFG) and inferior frontal gyrus (IFG)
Temporal parietal junction (TPJ) – inferior parietal lobule (IPL) and superior temporal gyrus (STG)

Functions: Bottom-up attentional processing.

External Attention System (EAS) : DAN and VAN

dorsal and ventral attention networks

Dorsal attention network (DAN) orange; ventral attention network (VAN) blue. From Aboitiz et al (2014)

Functions: Control of attention through flexible interaction between both systems enables the dynamic control of attention in relation to top-down goals and bottom-up sensory stimulation. Part of the ‘task positive’ cognitive control network (CCN).

Fronto-Parietal Network

Anterior dorso-lateral prefrontal cortex (aDLPFC)
Intra-parietal sulcus IIPS) and inferior parietal lobule (IPL)
Middle cingulate cortex (MCC)
Rostral inferior temporal cortex (rITC)

Functions: Top down signals for current task goals exert control by flexibly biasing information flow across multiple large-scale functional networks overcoming conflict from previous habits. Also allows for novel task control. Part of the ‘task positive’ cognitive control network (CCN).

Cingulo-Opercular Network (CON)

DLPFC
Anterior Insula
Dorsal anterior cingulate cortex (dACC)
Thalamus

Functions: Vigilance and sustained attention. Tonic alertness for working memory. Set maintenance in working memory related tasks. Response override after conflict detection.
