Cortical spreading depolarization (CSD) is an electrophysiologic phenomenon found mostly in the setting of neurologic injury resulting in the disturbance of ion homeostasis and leading to changes in the local vascular response. The bioelectric etiology of CSD shares similarities to those in epileptic disorders, yet the relationship between seizures and CSD is unclear, with several studies obser...

Deep brain stimulation (DBS) is a surgical treatment for Parkinson’s Disease. Static models based on quasi-static approximation are common approaches for DBS modeling. While this simplification has been validated for bioelectric sources, its application to rapid stimulation pulses, which contain more high-frequency power, may not be appropriate, as DBS therapeutic results depend on stimulus par...

Animal fat tissue consists of liquid, and solid fats combined in fibrous tissues. Unpleasant odors characterize changes quality, structure color occur when is stored. This study aims to test the quality chicken based on impedance measurements using Multi I/O Card PCI 6221 National Instrument driven by LabVIEW software, where AC injected into sample an electrode with a frequency variation 10 Hz ...

Bioelectric potentials are considered by BURR (2) to be a vital part of life processes, and any change affecting life processes is bound to exert an effect on these potentials. There is little doubt that radiation injury exerts a profound effect on the potentials of the avian embryo, as shown by ROMANOFF and BLESS (7) and on seeds as found by BLESS (1) and JONES et al. (6). The effect of tumor ...
