Functional connectivity of the resting-state (RS) brain is a vehicle to study brain dysconnectivity aspects of diseases such as schizophrenia and bipolar. Methods that are developed to measure functional connectivity are based on the underlying hypotheses regarding the actual nature of RS-connectivity including evidence of temporally dynamic versus static RS-connectivity and evidence of frequen...

Background: Autism Spectrum Disorder (ASD) occurs based on the continuous deficit in a person’s verbal skills, visual, auditory, touch, and social behavior. Over the last two decades, one of the most important approaches in studying brain functions in autistic persons is using functional Magnetic Resonance Imaging (fMRI). Objectives: It is common to use all brain regions in functional extracti...

Abstract Fault-karst reservoirs are featured by complex geological characteristics, and accurate fast simulation of such kind using traditional simulator methods is pretty hard. Herein, we tried to discrete the fault-karst structures into one-dimensional connected units connecting well, fracture cave based on reservoir static physical parameters injection-production dynamics. Two characteristic...

Hydrological connectivity is an essential indicator of wetland pattern and functional stability. The reduction usually means the degradation ecological function, internal energy flow, nutrient cycle disturbance. Taking Hanshiqiao as a case, we used Morphological Spatial Pattern Analysis (MSPA) with Connectivity Index (IIC, Integral Connectivity; PC, Probability Connectivity) to analyze change i...

Recent studies of the olfactory system report that differentiated sensory neurons have an identity evidenced by surface markers. These markers relate to the specificity of the neuron's odorant receptor. During axonal outgrowth the markers co-determine, with which of the second stage neurons synapses are formed. The markers and the resulting connectivity (or network structure) amount to static, ...

Several approaches exist to ascertain the connectivity of the brain, and these approaches lead to markedly different topologies, often incompatible with each other. Specifically, recent single-cell recording results seem incompatible with current structural connectivity models. We present a novel method that combines anatomical and temporal constraints to generate biologically plausible connect...

Behavioral alterations emerging after central or peripheral vision loss suggest that cerebral reorganization occurs for both the afferented and deafferented early visual cortex (EVC). We explored the functional reorganization of the central and peripheral EVC following visual field defects specifically affecting central or peripheral vision. Compared to normally sighted, afferented central and ...

Human higher cognition arises from the main tertiary association cortices including the frontal, temporal and parietal lobes. Many studies have suggested that cortical functions must be shaped or emerge from the pattern of underlying physical (white matter) connectivity. Despite the importance of this hypothesis, there has not been a large-scale analysis of the white-matter connectivity within ...

Eccentric connectivity index has been found to have a low degeneracy and hence a significant potential of predicting biological activity of certain classes of chemical compounds. We present here explicit formulas for eccentric connectivity index of various families of graphs. We also show that the eccentric connectivity index grows at most polynomially with the number of vertices and determine ...
