Imagine your brain as a bustling city where different neighborhoods represent different cognitive tasks. In this study, scientists explored how the brain seamlessly transitions from a relaxed state to an engaged state. They discovered that synchrony, or the coordinated activity between different brain regions, plays a crucial role in this process. By comparing the synchrony patterns during rest and specific tasks, they found that synchrony levels significantly increased during tasks. Interestingly, the increase in synchrony was more pronounced in higher-order cognitive networks compared to sensorimotor networks. This finding suggests that your brain prioritizes signaling among regions responsible for complex thinking when you’re tackling a task. Additionally, participants who had higher levels of pre-configured synchrony during rest performed better on cognitive tasks. These results provide valuable insights into the dynamic nature of the brain and its ability to adapt to different mental demands.

Although many resting state and task state characteristics have been studied, it is still unclear how the brain network switches from the resting state during tasks. The current theory shows that the brain is a complex dynamic system and synchrony is defined to measure brain activity. The study compared the changes of synchrony between the resting state and different task states in healthy young participants (N = 954). It also examined the ability to switch from the resting state to the task-general architecture of synchrony. We found that the synchrony increased significantly during the tasks. And the results showed that the brain has a task-general architecture of synchrony during different tasks. The main feature of task-based reasoning is that the increase in synchrony of high-order cognitive networks is significant, while the increase in synchrony of sensorimotor networks is relatively low. In addition, the high synchrony of high-order cognitive networks in the resting state can promote task switching effectively and the pre-configured participants have better cognitive performance, which shows that spontaneous brain activity and cognitive ability are closely related. These results revealed changes in the brain network configuration for switching between the resting state and task state, highlighting the consistent changes in the brain network between different tasks. Also, there was an important relationship between the switching ability and the cognitive performance.
