Book Synopsis Functional Brain Mapping: Methods and Aims by : Vassiliy Tsytsarev
Download or read book Functional Brain Mapping: Methods and Aims written by Vassiliy Tsytsarev and published by Springer Nature. This book was released on 2020-09-07 with total page 203 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides an essential overview of the broad range of functional brain imaging techniques, as well as neuroscientific methods suitable for various scientific tasks in fundamental and clinical neuroscience. It also shares information on novel methods in computational neuroscience, mathematical algorithms, image processing, and applications to neuroscience. The mammalian brain is a huge and complex network that consists of billions of neural and glial cells. Decoding how information is represented and processed by this neural network requires the ability to monitor the dynamics of large numbers of neurons at high temporal and spatial resolution over a large part of the brain. Functional brain optical imaging has seen more than thirty years of intensive development. Current light-using methods provide good sensitivity to functional changes through intrinsic contrast and are rapidly exploiting the growing availability of exogenous fluorescence probes. In addition, various types of functional brain optical imaging are now being used to reveal the brain’s microanatomy and physiology.

Book excerpt: Neuronal Networks in Brain Function, CNS Disorders, and Therapeutics, edited by two leaders in the field, offers a current and complete review of what we know about neural networks. How the brain accomplishes many of its more complex tasks can only be understood via study of neuronal network control and network interactions. Large networks can undergo major functional changes, resulting in substantially different brain function and affecting everything from learning to the potential for epilepsy. With chapters authored by experts in each topic, this book advances the understanding of: How the brain carries out important tasks via networks How these networks interact in normal brain function Major mechanisms that control network function The interaction of the normal networks to produce more complex behaviors How brain disorders can result from abnormal interactions How therapy of disorders can be advanced through this network approach This book will benefit neuroscience researchers and graduate students with an interest in networks, as well as clinicians in neuroscience, pharmacology, and psychiatry dealing with neurobiological disorders. Utilizes perspectives and tools from various neuroscience subdisciplines (cellular, systems, physiologic), making the volume broadly relevant Chapters explore normal network function and control mechanisms, with an eye to improving therapies for brain disorders Reflects predominant disciplinary shift from an anatomical to a functional perspective of the brain Edited work with chapters authored by leaders in the field around the globe – the broadest, most expert coverage available
Book Synopsis Resting-state Functional Connectivity by : Mona Maneshi
Download or read book Resting-state Functional Connectivity written by Mona Maneshi and published by . This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: "Trying to understand how normal brain function is disrupted in epilepsy, a growing number of studies have focused on the analysis of resting-state fMRI by calculating measures of functional connectivity. However, it is still unclear whether resting-state fMRI can help exploring alterations in brain functions in this disease. Moreover, it has not been investigated whether the methods of functional connectivity analysis are appropriate for detection of these variations. Finally, not enough research has been performed to understand the mechanisms underlying different analysis methods and to find how they should be interpreted. This dissertation looks into these issues in a systematic way and to this end three experiments were performed.The first study, in patients with idiopathic generalized epilepsy, aimed at providing a unified approach to explore changes in resting-state brain function of the regions normally involved in sustained attention. We used seed-based functional connectivity analysis, which allowed us to detect functional connectivity changes related to the duration of epilepsy. We identified three networks in which functional connectivity was related to the duration of epilepsy. Our findings were specific to these networks, as none of the additionally tested seeds resulted in correlation between the duration of epilepsy and functional connectivity.In order to have a network view of the changes all over the brain, we decided to go toward data-driven approaches and considered independent component analysis (ICA). In a study not included in this thesis, we first tried to solve the problems of available ICA-based functional connectivity approaches in conducting between-group comparisons. We proposed a method, called shared and specific ICA, or SSICA, which enabled us to systematically extract and classify components as shared by the groups and specific to a group. In study two, we included a finger-tapping dataset and generated realistic simulations (hybrid data) by adding arbitrary focal activations (patches) to the resting-state data of healthy subjects, and tested the validity of SSICA. In addition to examining the SSICA robustness with respect to several internal parameters and initializations, we provided several simulations to investigate the characteristics of SSICA in different real-case situations. We compared the results of SSICA with a current group-ICA method. Results showed that for both cases and in different situations, SSICA outperforms the current approach in terms of performance, sensitivity and robustness. The third study applied SSICA on data of patients with mesial temporal lobe epilepsy (MTLE) and compared the resting-state brain function between these patients and healthy controls. We applied SSICA multiple times with different internal parameters and initializations and this resulted in a large number of components specific to the patients and to the controls. To identify the most reliable and reproducible specific networks, we applied a spatial clustering analysis. Finally, we estimated the functional connectivity in each group using power spectrum analysis. We found two reliable MTLE-specific networks and one control-specific network. We showed that the two reliable MTLE-specific networks are in fact brain regions with higher functional connectivity in patients compared to controls whereas the regions involved in the control-specific network show the opposite. Overall, our studies indicate that resting-state functional connectivity can be used as a viable approach to detect alterations in resting brain function in epilepsy and that SSICA is a more appropriate method than current group-ICA approach to detect between-group differences. Moreover, our findings demonstrate that the use of SSICA, not only makes a priori hypotheses unnecessary but also permits differences between the groups to be detected with high reliability and sensitivity." --
Download or read book Brain Mapping written by Hugues Duffau and published by Springer Science & Business Media. This book was released on 2011-11-13 with total page 383 pages. Available in PDF, EPUB and Kindle. Book excerpt: The goal of this book is to make a link between fundamental research in the field of cognitive neurosciences, which now benefits from a better knowledge of the neural foundations of cerebral processing, and its clinical application, especially in neurosurgery – itself able to provide new insights into brain organization. The anatomical bases are presented, advances and limitations of the different methods of functional cerebral mapping are discussed, updated models of sensorimotor, visuospatial, language, memory, emotional, and executive functions are explained in detail. In the light of these data, new strategies of surgical management of cerebral lesions are proposed, with an optimization of the benefit–risk ratio of surgery. Finally, perspectives about brain connectivity and plasticity are discussed on the basis of translational studies involving serial functional neuroimaging, intraoperative cortico-subcortical electrical mapping, and biomathematical modeling of interactions between parallel distributed neural networks.
Book Synopsis Networks of the Brain by : Olaf Sporns
Download or read book Networks of the Brain written by Olaf Sporns and published by MIT Press. This book was released on 2016-02-12 with total page 433 pages. Available in PDF, EPUB and Kindle. Book excerpt: An integrative overview of network approaches to neuroscience explores the origins of brain complexity and the link between brain structure and function. Over the last decade, the study of complex networks has expanded across diverse scientific fields. Increasingly, science is concerned with the structure, behavior, and evolution of complex systems ranging from cells to ecosystems. In Networks of the Brain, Olaf Sporns describes how the integrative nature of brain function can be illuminated from a complex network perspective. Highlighting the many emerging points of contact between neuroscience and network science, the book serves to introduce network theory to neuroscientists and neuroscience to those working on theoretical network models. Sporns emphasizes how networks connect levels of organization in the brain and how they link structure to function, offering an informal and nonmathematical treatment of the subject. Networks of the Brain provides a synthesis of the sciences of complex networks and the brain that will be an essential foundation for future research.
Book Synopsis Feature Analysis of Functional MRI Data for Mapping Epileptic Networks by : Lauren S. Burrell
Download or read book Feature Analysis of Functional MRI Data for Mapping Epileptic Networks written by Lauren S. Burrell and published by . This book was released on 2008 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This research focused on the development of a methodology for analyzing functional magnetic resonance imaging (fMRI) data collected from patients with epilepsy in order to map epileptic networks. Epilepsy, a chronic neurological disorder characterized by recurrent, unprovoked seizures, affects up to 1% of the world's population. Antiepileptic drug therapies either do not successfully control seizures or have unacceptable side effects in over 30% of patients. Approximately one-third of patients whose seizures cannot be controlled by medication are candidates for surgical removal of the affected area of the brain, potentially rendering them seizure free. Accurate localization of the epileptogenic focus, i.e., the area of seizure onset, is critical for the best surgical outcome. The main objective of the research was to develop a set of fMRI data features that could be used to distinguish between normal brain tissue and the epileptic focus. To determine the best combination of features from various domains for mapping the focus, genetic programming and several feature selection methods were employed. These composite features and feature sets were subsequently used to train a classifier capable of discriminating between the two classes of voxels. The classifier was then applied to a separate testing set in order to generate maps showing brain voxels labeled as either normal or epileptogenic based on the best feature or set of features. It should be noted that although this work focuses on the application of fMRI analysis to epilepsy data, similar techniques could be used when studying brain activations due to other sources. In addition to investigating in vivo data collected from temporal lobe epilepsy patients with uncertain epileptic foci, phantom (simulated) data were created and processed to provide quantitative measures of the efficacy of the techniques.

Book Synopsis Invasive Studies of the Human Epileptic Brain by : Samden D. Lhatoo
Download or read book Invasive Studies of the Human Epileptic Brain written by Samden D. Lhatoo and published by Oxford University Press. This book was released on 2018-11-15 with total page 577 pages. Available in PDF, EPUB and Kindle. Book excerpt: No other neurological condition allows the same opportunities for an intracranial electrophysiological study of the human brain as epilepsy does. Epileptic surgery is designed to remove the epileptic focus from the human brain, thereby effecting either cure or substantial reduction of seizures in an individual with an otherwise intractable condition. Its use as a treatment modality dates from the late 19th century, and it has become a widely used treatment option throughout the world in the last 20-30 years. The complexity of epilepsy cases in surgical centres, and the need for invasive electrode studies for pre-surgical evaluation, are both greatly increasing. Invasive Studies of the Human Epileptic Brain is the definitive reference text on the use of invasive electroencephalographic (EEG) diagnostic studies in human epilepsy. Written by some of the most renowned epilepsy experts of the 20th and 21st centuries, the authors provide their expertise and insights into the identification and mapping of intracranial epileptiform and non-epileptiform activity, mapping of the human brain function, and approaches in the use of invasive electroencephalography in a variety of clinical situations. The book is organized into an easily readable series of chapters and is brilliantly illustrated with case studies; each providing an intuitively comprehensive approach to invasive brain studies.
