When study participants move the stump of an amputated limb, neurons in the brain remain dynamic and excitable. Individuals can become desensitized to the compound, however, perhaps because of long-term damage to nerve tissue. The Experiment to Evaluate the AC Loss of 2G HTS Windings in the Application of Rotating Electric Machines. Recent advances in global electric circuit coupling between the space environment and the troposphere. Kohane thinks the nanowire technology could be applied to the engineering of any electrically excitable tissue, including tissue in the brain and spinal cord. Between the electrode and the excitable tissue there are a number of obstacles in form of tissue resistivities and permittivities that can only be circumvented by magnetic fields but not by electric fields and currents. Created myooids were 12 mm long, with diameters of 0.1-1 mm, and were excitable by transverse electrical stimulation, and contracted to produce force. John Wikswo and his group are at present working in three areas: the study of the linear and non-linear electrical properties of cardiac tissue during stimulation, propagation, and recovery for threshold- and defibrillation-strength shocks. Brain tissue that underlies the positive electrode (anode) becomes more excitable and the reverse is true for brain tissue that underlies the negative electrode (cathode). III-V semiconductor heterojunction, electronic and opto-electronic circuits.

Identification and characterization of autoantigens in rheumatoid arthritis and related rheumatic connective tissue diseases. IMAGINE = Improved Methods for the Assessment of the Generic Impact of Noise in the Environment. And (4) To develop methods to evaluate medical devices used for ablation of body tissues and the measurement and evaluation of EM heating and the evaluation of devices used intentionally to heat body tissues. Mechanics of hard tissue / J. Musculoskeletal soft tissue mechanics / Richard L Lieber, Thomas J Burkholder. Mechanics of tissue / lymphatic transport / Geert W Schmid-Schonbein, Alan R Hargens. Calculation of activating functions and fibre responses showed that only nerve fibres with a directional component parallel to the electrode surface were excitable by a cathode, whereas fibres perpendicular to the electrode surface were excitable under an anode. Finally, array insertion in tissue was performed to demonstrate its robustness for optical access in deep tissue. In particular, apparatus for controlling the stomach is described in which a controller applies an electrical field to electrodes on the stomach wall so as to modify the reaction of muscle tissue therein to an activation signal, while not generating a propagating action potential in the tissue. Currently, his research focus is on the mechanisms by which electrical stimulation and the specific molecular chemistry of materials elicits changes within the molecular biology, structure and function of nerve and muscle (excitable) cells. Integrated Biomaterials in Tissue Engineering. When study participants move the stump of an amputated limb, neurons in the brain remain dynamic and excitable.

Individuals can become desensitized to the compound, however, perhaps because of long-term damage to nerve tissue. A quantitative understanding of the bulk excitability of skeletal muscle tissues is important for the design of muscle tissue bioreactor systems, implantable muscle stimulators, and other systems where electrical pulses are employed to elicit contractions in muscle tissue both in vitro and in vivo. While light has been used to activate tissue before, this was apparently the lowest light energy ever reported to control electrical activity in excitable tissue. Roles of Electric Field and Fiber Structure in Cardiac Electric Stimulation. We explicitly demonstrate that deep inside intact myocardial tissue preparations, strong electrical shocks do produce considerable negative bulk polarization previously inferred from surface recordings. The optical stimulation of genetically engineered cells has significantly changed our understanding of electrically excitable tissues, paving the way towards controlling heart rhythm disorders by means of photostimulation. Surgically removing the excitable brain tissue can be curative, but often, too many areas of the brain are involved to effectively remove the entire seizure focus. The magnet generates a powerful, fluctuating magnetic field that induces small electrical currents inside the brain. 7310555 Regulation of excitable tissue control of the heart based on physiological input Ben-Haim, et al 12 / 18 / 2007. John Wikswo and his group are at present working in three areas: the study of the linear and non-linear electrical properties of cardiac tissue during stimulation, propagation, and recovery for threshold- and defibrillation-strength shocks.

Ask questions and find answers from other users. Suggest a new site feature or improvement. Engineering aspects of electromagnetic fields that have therapeutic applications: diathermy (short wave, microwave, and ultrasound), electrosurgery (thermal damage processes), stimulation of excitable tissue, and electrical safety. IET Electrical Systems in Transportation, 1 (2). Pp 69-79 ISSN 2042-9738. 2011) Exploring the development of a cultural care framework for European caring science. International Journal of Qualitative Stus, Health and Well-being, 6 (4) ISSN 1748-2631. Selective stimulation of a small volume of tissue at depth has not proved possible because the magnetic field, and hence the induced electric field, decreases and become more diffuse with distance below the coil.

The Medical University of South Carolina - Transcranial magnetic stimulation in psychiatry Historically, interventions made on the brain have been fairly drastic - from holes bored in the skull by primitive healers, through to the drugs, electrical treatments and psychosurgery of more recent times.

When stimulated with an electrical current, the cells produced a measurable spike in voltage, and electrical communication between adjacent bundles of cardiac cells was markedly improved. Nellis, Mike and Bas, Ralph and Beyens, Kristel and Kaminski, Dan, eds. (2012) Electronically monitored punishment: international and critical perspectives. To carry this out it is necessary to describe quantitatively the electrical (nonlinear) behavior of the cell membrane as well as to describe the electrical load (i.e. the electrical structure and conductivities of the intracellular and extracellular medium). Specifically, optical mapping was utilized to compare action potential duration and quantify arrhythmia susceptibility of cardiomyocytes subjected to pulsatile mechanical strain, electrical stimulation, and dyssynchronous electrical and mechanical stimulation. A method is disclosed that allows the comparison of neural response measures made at one pulse duration to programs using pulse durations of arbitrary duration.
