Introduction: One of very important parts for humans live is sleeging.  Sleep deprivation (SD) is defined as sleep-loss status generally caused by personal or environmental reasons. It becomes an inherent problem to shift work, e.g. Intensive care unit (ICU) physicians or drivers, is very common in modern society and has a profound effect on cognitive function, attention, learning, and working memory.
Methods: The data set obtained from Stockholm University in the Sleepy Brain project was evaluated using brain image analysis software, FSL. Statistical double regression method was used to investigate the significant differences between different brain regions. According to the Yeo Atlas, the components of the independent group analysis were assigned to seven brain networks. For this purpose, the brain communication matrix, before and after sleep deprivation, was calculated for two basic quantities. The first quantity is the intera-network communication for each of the independent components of each network, and the second quantity is the inter-network communication, which indicates the weakening or strengthening of the communication between the seven introduced networks.
Results: There was a significant difference between N1 and N5 networks (5 networks related to visual function and limbic network) among 5 networks for which intra-network comparison is possible. There are also significant differences between networks for N1-N7, N2-N6, N3-N7 and finally N4-N6 networks in sleep deprivation and normal conditions.
Conclusion: The relationship between visual and limbic networks between regions and brain networks that are statistically significant in people with sleep deprivation and normal people can be interpreted as affecting the cognitive functions of memory and attention.
