External task switches activate default mode regions without enhanced processing of the surrounding scene

A collection of 4 brain maps. Each brain map is a 3D array of values representing properties of the brain at different locations.

### Collection description

<p>We aimed to replicate the DMN task-switch effect and test whether it reflects increased representation of broader context, specifically of a scene presented behind the focal task. In the Core DMN, we found significant activity for all task switches, compared to task repeats, and stronger activity for switches between rest and task. DMN activity at within-domain switches was no less than at between-domain switches.</p>

本数据集包含四幅大脑图谱。每幅大脑图谱均以三维数值数组的形式呈现，用于描述大脑在不同位置处的特性。

### 数据集描述

旨在复制默认模式网络（DMN）的任务切换效应，并检验其是否反映了更广泛背景的增加性表征，尤其是焦点任务背后的场景。在核心DMN中，我们发现所有任务切换相较于任务重复均表现出显著的活动，且在休息与任务之间的切换活动中，活动强度更为突出。在同一领域内的切换活动强度并不亚于跨领域的切换活动。
