可改变的行为，包括身体活动和久坐行为，是健康的重要决定因素。健康信息是影响这些行为的重要工具。功能性神经影像学研究表明，大脑默认模式和显著性系统区域的活动与关注健康促进信息独立相关。然而，目前尚不清楚这些大脑系统在接触说服性信息时如何相互作用，以及这种相互作用如何与随后的行为变化相关。在这里，我们研究如何人与人之间的差异，在默认模式和显着性系统之间的相对整合，同时查看健康信息与健康行为的变化。使用腕戴式加速计，我们客观地记录了150名参与者（平均年龄=33.17岁，64%为女性; 43%为黑人，37%为白色，7%为亚洲人，5%为西班牙裔，8%为其他人）平均连续10天的身体活动。然后，参与者在接受功能性磁共振成像（fMRI）时查看鼓励身体活动的健康信息，并完成了额外的一个月，其中记录了身体活动，并通过每日短信提醒来加强健康信息。在健康信息暴露过程中具有较高默认模式和显著性系统整合的个体在fMRI后的一个月内比具有较低大脑整合的参与者更有可能减少久坐行为并增加轻度体力活动。显着性和默认模式系统之间的相互作用与信息的接受性和随后的行为变化，突出的价值扩大的重点从单一的大脑区域在研究健康行为变化的作用，以更大规模的连接。
Modifiable behaviors, including physical activity and sedentary behavior, are important determinants of health. Health messages are important tools for influencing these behaviors. Functional neuroimaging research suggests that activity in regions of the brain’s default mode and salience systems are independently associated with attending to health promoting messages. However, it remains unclear how these brain systems interact during exposure to persuasive messages, and how this interaction relates to subsequent behavior change. Here, we examine how between-person differences in the relative integration between default mode and salience systems while viewing health messages relates to changes in health behavior. Using wrist-worn accelerometers, we objectively logged physical activity in 150 participants (mean age=33.17 years, 64% women; 43% Black, 37% white, 7% Asian, 5% Hispanic, and 8% other) continuously for an average of 10 days. Participants then viewed health messages encouraging physical activity while undergoing functional magnetic resonance imaging (fMRI) and completed an additional month where physical activity was logged and the health messages were reinforced with daily text reminders. Individuals with higher default mode and salience system integration during health message exposure were more likely to decrease their sedentary behavior and increase light physical activity in the month following fMRI than participants with lower brain integration. Interactions between the salience and default mode systems are associated with message receptivity and subsequent behavior change, highlighting the value of expanding the focus from the role of single brain regions in studying health behavior change to larger-scale connectivity.
