Book excerpt: During our entire lifetime, we continuously rely on the brain to facilitate functioning of almost every part of our body. A proper development of the brain and its safe protection are, therefore, of utmost importance. Mechanics plays an important role in both of these aspects. Although evidence for the presence and significance of mechanics in the brain dates back several decades, a thorough understanding of its precise role has not yet been established. Computational modeling provides a powerful tool to investigate the role of mechanics and to probe causal relationships between mechanics and brain development or brain injury that are extremely difficult to obtain with experiments alone. We use and develop computational tools to investigate the role of mechanics in the brain at and across three spatial scales: the subcellular level of individual proteins, the cellular scale of the nerve cell and its axon, and the tissue scale of whole brain. We design a novel finite element framework that allows to assign a molecular mechanism to individual elements that represents the characteristic dynamic behavior of a particular protein at the subcellular level. By embedding these mechanisms into our computational model of the axon, we investigate their effects on emergent properties at the cellular level, such as axon stiffness, viscosity, and damage. Our results demonstrate mechanisms by which dynein and myosin motors, microtubule dynamics, and microtubule disassembly affect axon outgrowth. Our axon model further predicts critical thresholds for axon damage that are consistent with values reported in the literature. We use these results to develop a constitutive model for axon damage that can be embedded in a continuum model at the tissue level. Finally, we propose a continuum multifield model at the tissue level that accurately predicts the development of brain volume and structure during weeks 10-29 of gestation. We couple cell migration to mechanics and volume growth. Our model predicts a wide variety of complex folding patterns ranging from single creases to sinusoidal folding and provides additional insights into the role of mechanics during the complex process of cortical folding.

Download or read book Multiscale Models of Brain Disorders written by Vassilis Cutsuridis and published by Springer Nature. This book was released on 2019-10-11 with total page 222 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on our current understanding of brain dynamics in various brain disorders (e.g. epilepsy, Alzheimer’s and Parkinson’s disease) and how the multi-scale, multi-level tools of computational neuroscience can enhance this understanding. In recent years, there have been significant advances in the study of the dynamics of the disordered brain at both the microscopic and the macroscopic levels. This understanding can be furthered by the application of multi-scale computational models as integrative principles that may link single neuron dynamics and the dynamics of local and distant brain regions observed using human EEG, ERPs, MEG, LFPs and fMRI. Focusing on the computational models that are used to study movement, memory and cognitive disorders as well as epilepsy and consciousness related diseases, the book brings together physiologists and anatomists investigating cortical circuits; cognitive neuroscientists studying brain dynamics and behavior by means of EEG and functional magnetic resonance imaging (fMRI); and computational neuroscientists using neural modeling techniques to explore local and large-scale disordered brain dynamics. Covering topics that have a significant impact on the field of medicine, neuroscience and computer science, the book appeals to a diverse group of investigators.

Available in PDF, EPUB and Kindle. Book excerpt: The present study addresses the large strain nonlinear mechanical response of the cerebral cortex at the macroscopic tissue level and at the microscopic cell level. Unconfined uniaxial compression tests were conducted in vitro on cortical samples of porcine brains. The tests consisted of load-unload and relaxation segments to 50% nominal deformation at 0.01 to 10 s-1 strain rates. The tissue exhibited moderate volumetric compressibility, marked hysteretic features, and substantial nonlinearities. Indentation tests - with displacement histories mirroring those imposed in compression - were performed on the cortex of porcine brains in vivo, in situ and in vitro, in order to assess and contrast the mechanical properties of the live and dead tissue. The tissue response shared similar qualitative nonlinear viscoelastic features under all testing conditions, although, quantitatively, the response was found to be significantly stiffer in situ than in vivo. Test protocols were also developed at the neuronal cell level using atomic force microscopy. The response of individual somata to cyclic load-unload and relaxation test sequences was found to be nonlinear with time dependencies and hysteretic patterns similar to those measured at the tissue level. A large strain kinematics nonlinear continuum model was proposed to capture the features of the tissue and cell responses. The model was numerically implemented into a three-dimensional finite-element framework. The continuum formulation was found to successfully account for the main experimental observations gathered in vitro at the tissue and cell levels. The present study provides novel insights into the tissue rheology in vivo, in situ and in vitro, at large strains, in the quasi-static and dynamic strain rate regime and reports the first body of observations on the large strain nonlinear viscoelastic properties of brain tissue in vivo. These observations could be directly compared to those pertaining to the tissue response in situ and in vitro, thereby providing a unique quantitative basis for further refinements of existing biomechanical models relying only on in vitro/situ measurements. The consistent set of mechanical data collected, and the constitutive framework proposed at the tissue and cell levels might support the development of multiscale numerical models to study traumatic brain injury.

Download or read book Neural Tissue Biomechanics written by Lynne E. Bilston and published by Springer Science & Business Media. This book was released on 2011-07-23 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: Damage to the central nervous system resulting from pathological mechanical loading can occur as a result of trauma or disease. Such injuries lead to significant disability and mortality. The peripheral nervous system, while also subject to injury from trauma and disease, also transduces physiological loading to give rise to sensation, and mechanotransduction is also thought to play a role in neural development and growth. This book gives a complete and quantitative description of the fundamental mechanical properties of neural tissues, and their responses to both physiological and pathological loading. This book reviews the methods used to characterize the nonlinear viscoelastic properties of central and peripheral neural tissues, and the mathematical and sophisticated computational models used to describe this behaviour. Mechanisms and models of neural injury from both trauma and disease are reviewed from the molecular to macroscopic scale. The book provides a comprehensive picture of the mechanical and biological response of neural tissues to the full spectrum of mechanical loading to which they are exposed. This book provides a comprehensive reference for professionals involved in pre prevention of injury to the nervous system, whether this arises from trauma or disease.
