Linked networks for learning and expressing location-specific threat: Threat learning versus object learning during approach periods

<p>Activity differences between approaching flowers versus objects during threat and spatial memory aspects of the task. Greater activity was seen when approaching flowers compared with objects in a range of areas, including the insula, medial parietal cortex, PCC, vmPFC, bilateral anterior hippocampus, and amygdala.When approaching objects, a different network was observed with greater activity in the left middle frontal gyrus, middle temporal gyrus, inferior parietal lobule and inferior frontal gyrus, right precentral gyrus, inferior frontal gyrus, and an area extending across lingual and parahippocampal gyri.</p>

<p>在任务中的威胁和空间记忆方面，接近花朵与接近物体之间的活动差异。在岛叶、内侧顶叶皮层、后扣带回皮层、背内侧前额叶皮层、双侧前海马体和杏仁核等广泛脑区，接近花朵时的活动水平显著高于接近物体时的水平。当接近物体时，观察到不同的神经网络活动，其中左侧中间额叶回、中间颞叶回、下顶叶叶间、下额叶回、右侧前中央回、下额叶回以及横跨舌叶和海马旁回的区域活动水平较高。</p>
