Although there are considerable individual differences in eye movements during text reading, their neural correlates remain unclear. In this study, we investigated the relationship between the first-pass fixation duration (FPFD) in natural reading and resting-state functional connectivity (RSFC) in the brain. We defined the brain regions associated with early visual processing, word identification, attention shifts, and oculomotor control as seed regions. The results showed that individual FPFDs were positively correlated with individual RSFCs between the early visual network, visual word form area, and eye movement control/dorsal attention network. Our findings provide new evidence on the neural correlates of eye movements in text reading and indicate that individual differences in fixation time may shape the RSFC differences in the brain through the time-on-task effect and the mechanism of Hebbian learning.

阅读中首过注视持续时间的个体差异与静息状态功能连接有关

尽管在文本阅读过程中眼球运动存在相当大的个体差异，但它们的神经相关性仍不清楚。在这项研究中，我们调查了自然阅读中的首过注视持续时间 (FPFD) 与大脑中的静息状态功能连接 (RSFC) 之间的关系。我们将与早期视觉处理、单词识别、注意力转移和动眼神经控制相关的大脑区域定义为种子区域。结果表明，个体FPFDs与早期视觉网络、视觉词形区域和眼动控制/背侧注意网络之间的个体RSFCs呈正相关。
