A Graph Signal Processing View on Functional Brain Imaging
Modern neuroimaging techniques provide us with unique views on brain structure and function; i.e., how the brain is wired, and where and when activity takes place. Data acquired using these techniques can be analyzed in terms of its network structure to reveal organizing principles at the systems level. Graph representations are versatile models where nodes are associated to brain regions and e...
متن کاملSegmentation of Magnetic Resonance Brain Imaging Based on Graph Theory
Introduction: Segmentation of brain images especially from magnetic resonance imaging (MRI) is an essential requirement in medical imaging since the tissues, edges, and boundaries between them are ambiguous and difficult to detect, due to the proximity of the brightness levels of the images. Material and Methods: In this paper, the graph-base...
متن کاملA Cellular Perspective on Brain Energy Metabolism and Functional Imaging
The energy demands of the brain are high: they account for at least 20% of the body's energy consumption. Evolutionary studies indicate that the emergence of higher cognitive functions in humans is associated with an increased glucose utilization and expression of energy metabolism genes. Functional brain imaging techniques such as fMRI and PET, which are widely used in human neuroscience studi...
متن کاملExplorative signal processing in functional MR imaging
Identification and separation of artifacts as well as quantification of expected, i.e., stimulus-correlated, and novel information on brain activity are important for both new insights in neuroscience and future developments in functional magnetic resonance imaging (MRI) of the human brain. Here, we present several examples in which gross head motion or physiologic motion (e.g., pulsation, resp...
متن کاملNeuronal coordination in the brain: A signal processing perspective
Every day you wake up, go to work, visit friends, eat an apple, basically perform your daily activities. During the day, in normal conditions, your body and mind, altogether, acts in conjunction and harmony to perform these activities. Such an harmony is dynamically realized by your body–mind entity. One of the principal centralizer of this harmony is the central nervous system, namely your bra...
