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.

Available in PDF, EPUB and Kindle. Book excerpt: Traumatic brain injury (TBI) is a significant cause of death and morbidity in both the civilian and military populations. The major causes of TBI, such as motor vehicle accidents, falls, sports concussions, and ballistic and explosive blast threats for military personnel, are well established and extensively characterized; however, there remains much to be learned about the specific mechanisms of damage leading to brain injury, especially at the cellular level. In order to understand how cells of the central nervous system (CNS) respond to mechanical insults and stimuli, a combined modeling/experimental approach was adopted. A computational framework was developed to accurately model how cells deform under various macroscopically imposed loading conditions. In addition, in vitro (cell culture) models were established to investigate damage responses to biologically relevant mechanical insults. In order to develop computational models of cell response to mechanical loading, it is essential to have accurate material properties for all cells of interest. In this work, the mechanical responses of neurons and astrocytes were quantified using atomic force microscopy (AFM) at three different loading rates and under relaxation to enable characterization of both the elastic and viscous components of the cell response. AFM data were used to calibrate an eight-parameter rheological model implemented in the framework of a commercial finite element package (Abaqus). Model parameters fit to the measured responses of neurons and astrocytes provide a quantitative measure of homogenized nonlinear viscoelastic properties for each cell type. In order to ensure that the measured responses could be considered representative of cell populations in their physiological environment, cells were also grown and tested on substrates of various stiffness, with the softest substrate mimicking the stiffness of brain tissue. Results of this study showed both the morphology and measured force response of astrocytes to be significantly affected by the stiffness of their substrate, with cells becoming increasingly rounded on soft substrates. Results of simulations suggested that changes in cell morphology were able to account for the observed changes in AFM force response, without significant changes to the cell material properties. In contrast, no significant changes in cell morphology were observed for neurons. These results highlight the importance of growing cells in a biologically relevant environment when studying mechanically mediated responses, such as TBI. To address this requirement, we developed two model systems with CNS cells grown in soft, 3D gels to investigate damage arising from dynamic compressive loading and from a shock pressure wave. These damage protocols, coupled with the single cell computational models, provide a new tool set for characterizing damage mechanisms in CNS cells and for studying TBI in highly controllable in vitro conditions.

This book was released on 2021 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Degenerative cervical myelopathy (DCM) is a common cause of spinal cord injury in elderly populations involving phenomena of biomechanical interactions between the central nervous system of the spine and the flow of cerebrospinal fluid. This thesis aims to provide a morphometric description of the cervical canal and a mechanical description of the spinal meninges which could lead to the future development of numerical models with fluid-structure interactions. In the first part, a methodology was developed to describe the morphometry of the cervical canal with new metrics using MRI. This methodology could also be used for the improvement of the diagnosis of DCM and for the definition of the subject-specific geometry in biomechanical modeling. In the second part, two mechanical test protocols were performed to describe the mechanical properties in uniaxial and biaxial tension of the porcine spine meninges chosen as a model similar to humans. These experimental data play a crucial role in numerical biomechanical modeling. In the third part, the mathematical formulation of a fluid-structure interaction problem between a Newtonian fluid and a linear elastic solid was presented. Thus, a preliminary and simplified FSI model was developed with an explicit solver (RADIOSS) as proof of concept. This thesis could thus help the scientific community to develop biomechanical models of the spinal canal by taking into account the role of cerebrospinal flow and nervous tissues in healthy or pathological cases.

Download or read book Mechanosensitivity of the Nervous System written by Andre Kamkin and published by Springer Science & Business Media. This book was released on 2008-09-22 with total page 355 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents the latest findings in mechanosensitivity of the nervous system. The nervous system stands out from a number of tissues because besides reacting to the mechanical stress it is transmitting its own response to other organs and tissues, which are located downstream of its signaling pathway. For this reason any type of mechanical stimulation of the nervous system, which is capable of triggering a physiological response, has high scientific and practical significance, since it allows its use beyond a particular experimental model anywhere where it is contributing to a particular pathological condition. This book is a unique collection of reviews outlining the current knowledge and the future developments in this rapidly growing field. Currently, investigations of the effects of mechanical stress on the nervous system are focused on several issues. The majority of studies investigate the effects of mechanical stimulation on mechanosensitive channels, as its primary target and interactive agent, and aim on description of downstream intracellular signaling pathways together with addressing general issues of biomechanics of the nervous system. Knowledge of biomechanics, and mechanisms, which underlie it on organism, organ, tissue and cellular level, is necessary for understanding of the normal functioning of living organisms and allows to predict changes which arise due to alterations of their environment, and possibly will allow to develop new methods of artificial intervention. The book brings up the problem closer to the experts in related medical and biological sciences as well as practicing doctors besides just presenting the latest achievements in the field.
