Identification of mild cognitive impairment disease using brain functional connectivity and graph analysis in fMRI data
Background: Early diagnosis of patients in the early stages of Alzheimer's, known as mild cognitive impairment, is of great importance in the treatment of this disease. If a patient can be diagnosed at this stage, it is possible to treat or delay Alzheimer's disease. Resting-state functional magnetic resonance imaging (fMRI) is very common in the process of diagnosing Alzheimer's disease. In th...
متن کاملPain enhances functional connectivity of a brain network evoked by performance of a cognitive task.
Experimental and clinical evidence indicates that pain can affect cognitive processes, but the cortical networks involved in pain-cognition interactions are unclear. In this study, we determined the effect of pain on the activity of cortical areas involved in cognition acting as a whole (i.e., a network). Subjects underwent functional magnetic resonance imaging (fMRI) while engaged in an attent...
متن کاملBrain Functional Connectivity Changes During Learning of Time Discrimination
The human brain is a complex system consist of connected nerve cells that adapts with and learn from the environment by changing its regional activities. Synchrony between these regional activities called functional network changes during the life, and with learning of new skills. Time perception and interval discrimination are among the most necessary skills for the human being to perceive mot...
متن کاملInvestigating the functional communication network in patients with knee osteoarthritis using graph-based statistical models
Introduction: Osteoarthritis of the knee is the most prevalent type of arthritis that causes persistent pain and reduces the quality of life. However, no treatment alleviates symptoms or stops the disease from progressing. Functional magnetic resonance imaging (fMRI) studies can provide information on neural mechanisms of pain by assessing correlation patterns among the different regions of the...
متن کاملThe Effect of Cognitive Tasks on the Ocular Vestibular Evoked Myogenic Potentials in Healthy People
Introduction: The majority of the daily life activities involve the concurrent performance of simultaneously challenging motor and cognitive activities, such as talking while walking, which requires the vestibular system for balance. Functional balance allows the brain to interpret and integrate the sensory information from our physical and social environment. This study aimed to investig...
