Sleep is one of the most basic human needs to continue life, so that proper sleep is necessary to maintain the energy needed to perform essential tasks, physical and mental health, and reduces anxiety and nervous pressure. Inadequate quality of sleep, which manifests itself mostly in the form of insomnia, is one of the causes of fatal road, rail and air driving accidents, academic retardation and other occupational accidents, and it causes a decrease in the quality of life and impairment of human memory and learning. Considering that the quality of sleep is closely related to mental and physical health, and poor sleep quality causes various mental illnesses, it is very important to identify brain areas that are related to sleep quality. Also, the quality of sleep affects human emotions, and it has been shown that bad sleep causes negative emotions such as anger, fear, and sadness. Therefore, to investigate the brain regions related to sleep quality, data related to the volume of gray matter in the amygdala and hippocampus regions of their brains were obtained from ۵۰ male and ۵۰ female individuals. According to past studies, these areas are very important in sleep quality. Therefore, by using different statistical tests and their analysis, the results showed that the overall sleep quality score has a direct relationship with negative emotions. Also, the analysis of the data obtained from the volume of gray matter showed the existence of a relationship between the sleep quality score and the left hippocampus in women. Also, these results showed that gender variable should be considered in statistical analyzes related to sleep quality in future studies.
