Sensing neural activity within mechanically active tissues poses particular hurdles because most electrodes are much stiffer than biological tissues. As the tissue deforms, the rigid electrodes may damage the surrounding tissue. The problem is exacerbated when sensing neural activity in experimental models of traumatic brain injury (TBI) which is caused by the rapid and large deformation of brain...
Traumatic brain injury (TBI) is caused by mechanical forces, producing tissue deformation at the moment of injury. Complex cellular, neurochemical and metabolic alterations are initiated by the deformation and result in delayed cell death and dysfunction. Using an in vitro model of TBI based on organotypic brain slice cultures, we have quantitatively studied the relationship between tissue deformation...
Traumatic brain injury (TBI) is caused by in response to mechanical loading of the head. An extended biological cascade is initiated by the deformation and results in delayed cell death and dysfunction. Using an in vitro model of TBI based on organotypic brain slice cultures, we have quantitatively studied the relationship between tissue deformation and outcome. In the current study, we asked the...
Traumatic brain injury (TBI) is the result of sudden external mechanical forces applied to the head. Compression, stretching and shear deform the brain tissue inducing cellular damage that may develop within a couple of days following the initial trauma. TBI can be modeled in vitro by rapidly stretching brain slice cultures grown on silicone membranes. Stretchable micro-electrode arrays (SMEAs) prepared...
