“…The left FFG is located in the occipitotemporal lobe and plays a key role in the lexical processing of reading, especially responsible for word form recognition [48][49][50]. These have been found to be positively associated with increased connectivity in the left occipitotemporal area [51]. Thus, enhanced connectivity within the left occipitotemporal region might reflect reading dysfunction, which coincided with previous studies in blind patients [52], indicating that abnormalities in this region may be a neuroplastic alteration contributing to compensatory performance after visual impairment.…”

Background: Normal tension glaucoma (NTG) is considered a neurodegenerative disease with glaucomatous damage extending to diffuse brain areas. Therefore, this study aims to explore the abnormalities in the NTG structural network to help in the early diagnosis and course evaluation of NTG. Methods: The structural networks of 46 NTG patients and 19 age- and sex-matched healthy controls were constructed using diffusion tensor imaging, followed by graph theory analysis and correlation analysis of small-world properties with glaucoma clinical indicators. In addition, the network-based statistical analysis (NBS) method was used to compare structural network connectivity differences between NTG patients and healthy controls. Results: Structural brain networks in both NTG and NC groups exhibited small-world properties. However, the small-world index in the severe NTG group was reduced and correlated with a mean deviation of the visual field (MDVF) and retinal nerve fiber layer (RNFL) thickness. When compared to healthy controls, degree centrality and nodal efficiency in visual brain areas were significantly decreased, and betweenness centrality and nodal local efficiency in both visual and nonvisual brain areas were also significantly altered in NTG patients (all p < 0.05, FDR corrected). Furthermore, NTG patients exhibited increased structural connectivity in the occipitotemporal area, with the left fusiform gyrus (FFG.L) as the hub (p < 0.05). Conclusions: NTG exhibited altered global properties and local properties of visual and cognitive-emotional brain areas, with enhanced structural connections within the occipitotemporal area. Moreover, the disrupted small-world properties of white matter might be imaging biomarkers for assessing NTG progression.

“…Analyzing brain structural and functional properties to identify general patterns and draw population-level inferences has been a major focus of human neuroimaging research. Human brain, however, displays significant inter-individual differences in both its structural (1)(2)(3)(4) and functional (5-7) facets, which underlie the complex and astonishing variability of human behavior. In recent years, scientific community in cognitive neuroscience has prompted a shifting from population-to individual-level inferences, aiming at studying individual brain fingerprints to aid predicting unique individual traits.…”

We present a method to map the regional similarity between resting state fMRI activities of different individuals. The similarity was measured using cross-entropy. Group level patterns were displayed based on the Human Connectome Project Youth data. While we only showed the cross-subject brain entropy (BEN) mapping results in this manuscript, the same concept can be directly extended to map the cross-sessional BEN and the cross-regional cross-subject or subject-session BEN.
