Depending on the current model, IPGs have an ability to accommodate either one or two electrodes. After this, the IPG is programmed transcutaneously via a PDA-like device with a magnet. The patient is given a controller with which they can use to turn the device on and off. Some IPGs can also be programmed to allow the patient to change the…

Cheryl Baker Introduction to Natural Science January 30, 2017 Unit 3 Discussion A. Controversy in science is healthy. It involves disagreements on how we should interpret data, over which ideas are supported the best by the evidence that is available, and what ideas are worth further investigation. It compels scientists to carefully examine data and perform additional research to help scientific study progress. And as stated in the text, controversy “is an essential part of the process of…

The electroconvulsive therapy has been one of the most controversial procedures in human history and is still performed, because of its effective treatment of depression and other mental disorders. The method of performance of ECT has changed over time, although its perception has not altered a lot. The influence of mass media, movies and books strongly determine the general public’s opinion about the electroshock therapy. Although the procedure has been performed since the late 1930s, its…

Both disorders generally characterized by the dysfunction of cortical areas that are involved in memory. tDCS applies a weak electrical current to the brain area of interest via electrodes. The stimulation applied causes a modulation of neural oscillations in the brain area stimulated. These oscillations cause long lasting plastic effects involving synaptic modification, which is also known as neuroplasticity. Past studies have revealed…

perspiration the participant due to response to the electrode), which contained two electrodes, which were placed on the participants forearm (Luck 2015.) Soon after the participants were shocked they then had to be subject to physiological responding that was then recorded. In experiment two the participants were put into two different distinct groups (instruction/ removal, control.) This time instead of the participants having the electrode on their forearm it was moved to their head. The…

Therefore, all the chosen electrodes reported significant latency difference based on old/new brands. The result suggested that old brands elicited significantly shorter latency than new brands at F1 t(200) = 73.39, p < .001, FCz t(200) = 69.92 p < .001, FC2 t(200) = 58.40, p < .001…

getting trapped into the molten weld pool. The consumable electrode is in the form a wire and is fed automatically through a tube. Electric currents vary from 300 A to 2000 A depending upon the penetration of the heat required. The power supply is most often single phase or a three phase with a rating of approx. 440 V which determines the size of the weld pool. Since the welding is to be done a circular part, the part is rotated around the electrode and the unfused flux can be recovered,…

methyl blue, humic acid, etc. facilitate the electrons transferred from the microbial cells to the electrode (Park and Zeikus 2000). Most of these mediators are very expensive and highly toxic to humans. Mediator-free microbial fuel cells, however, do not require a mediator, and therefore they are less expensive and much safer. The mediator-free microbial fuel cells transfer electrons to the electrode through electrochemically-alive bacteria. (“Mediator vs. Mediator-Less Microbial Fuel Cells”…

INTRODUCTION: The various competing sound present in our environment is being constantly untangled by our brain, and attributed into distinct perceptual streams analogous to the distinct sound sources in listeners’ environment (Bregman, 1990; Moore & Gockel, 2002; Carlyon, 2004). The process with which the nervous system makes sense of complex patterns of acoustic stimulation is called auditory scene analysis (Bregman, 1990). Thus, segregating the sounds arising from various sources in the…

in 5% or more of implanted patients. One of the biggest worries is that the during placement of the DBS electrodes there will be bleeding or alternatively a stroke that may lead to weakness, numbness, changes in vision, and/or changes in speech. The DBS device can fracture/break, migrate out of position, or malfunction requiring an another surgical procedure to replace or reposition the electrode. DBS frequently affects speech, and particularly verbal fluency (getting words out of the mouth).…
