I’m All Ears for Cochlears; Making Our Way to A Hearing World Imagine this, a world where people can't hear anything. Where people don't know what talking, music, or even the rustling of leaves sounds like. A deaf person lives in that world. Their world is silent. Most people get hearing loss once they grow older or are involved in some type of trauma, but what most people do not know is, “15% of children between the ages of 6-19 have a measurable hearing loss in at least one ear”…

Scientists connected electrodes to a man’s brain and with a click of a button; his dopamine receptors fired causing immense pleasure. The ethical conundrum of this experiment is debating whether the electrode man is happy or not. He was experiencing great amounts of low quality pleasure, but he did not have any fulfilment compared to high quality pleasures. Mill would argue that the electrode man was not achieving the good life because his experience was…

this proposal, we report the design of two bioanalytical sensors: (1) a fluorescence optrode-based optical fiber sensor and (2) a carbon-based optically transparent electrode. The first provides a means for spatially organizing microorganisms to monitor their social behavior in response to different chemical environments. The electrode sensor enables the detection of signaling molecules that are responsible for, or a consequence of, sociomicrobial behavior. Upon their completion, these sensors…

Although psychosurgery had multiple negative implications, the procedure was still progressing. In the late 1940s, noninvasive procedures were beginning to advance in neurosurgical devices. The confined lesion allowed for manageable side effects and less fatalities. Additionally, there was an increased advancements in neurobiological research on emotion, allowing for focus on distinct areas of the brain. Papez and later MacLean led to clarifying evidence of appropriate ranges to operate on that…

self-corrosion rate of Al, Alloy 1 and Alloy 2 electrodes in 2 M NaCl electrolyte, respectively. Corrosion rates were obtained by weight loss measurements in 2 M NaCl solution after 60 min. As seen in Table 1, the corrosion rate increases in the following order: Al ＜Alloy 1 ＜ Alloy 2. Fig. 2 indicates that open circuit potential of Alloy 1, 2 (especially Alloy2) is more negative than that of Al. It can be seen that the potential of the Al electrode shifts in the positive direction and achieves a…

incision is made behind the ear to open the mastoid bone leading to the middle ear space. Once the middle ear space is exposed, an opening is made in the cochlea and the implant electrodes are inserted. The electronic device at the base of the electrode array is then placed under the skin behind the ear (Levenson). The electrode array can slide into the cochlea without causing damage because it is especially designed to be thin, tapered and flexible. The receiver/stimulator sits in the bone just…

Introduction: The use of electromyography (EMG) to monitor muscle tissue from surface skin provides important information about the components of electrical activity—namely motor unit (MU) activation—during a muscle contraction (Cashaback, Cluff & Potvin, 2013). Observing electrical activity of a muscle with EMG is a user friendly and non-invasive tool researchers use when investigating muscle physiology (Camata et al., 2009). EMG is commonly used to correlate EMG signal with fatigue by…

the pristine Cu. As shown in the Scheme 1, when the Cu NP collides on the inert electrode where the appropriate potential, adaptable for the both the oxidation of Cu and electrocatalytic oxidation of glucose by Cu oxide is applied, the blip plus staircase current response is available by the self-oxidation of Cu NP and electrocatalytic reaction by oxidized Cu NP, respectively. To achieve this, the choice of inert electrode and appropriate potential is important, and Au UME was suitable for this.…

of electrons. Oxidation occurs at the anode and reduction at the cathode. A zinc electrode is placed in zinc sulphate (ZnSO₄) and a copper electrode is placed in copper sulphate (CuSO₄). These are half cells which are designed to handle oxidation half-cell and reduction half-cell reaction separately. The oxidation of zinc happens at the half-cell anode: Zn (s) → Zn2++2e- The oxidation of zinc causes the zinc electrode to dissolve to produce Zn2+ ions which enters the solution in which zinc and…

Discussion of Results and Scientific Explanation To achieve the goal of determining an unknown acid or base, anion and cation test were performed. These tests allowed for the components of the solutions to be identified, therefore, achieve the second goal. The pH was also used in to help find the identity of the unknown solutions and it was used to draw conclusions about the solutions. Dilutions were used to help understand the different behaviors of different concentrations. Household items…
