    Auditory Brainstem Response, commonly abbreviated as ABR is a test used to determine the thresholds of hearing and evaluate the pathways of the auditory system in the brainstem linked to disorders. The test is categorised as an objective test as it measures the waveforms produced in response to a stimulus and doesn’t rely on the patient to cooperate. (Iwona Kostorz, 2013). ABR is essentially used for neonatal screening, threshold estimation, intraoperative monitoring and determining the type of hearing

    Auditory brainstem response (ABR) refers to responses that originate from the brainstem when a short stimulus is played to a patient’s ears. Results are extracted by recording electrical activity in the brain using electrodes that are placed on the scalp, which produce an EEG that consists of different waveforms but the background EEG is separated to detect only the auditory brainstem response. The stimulus presented to the patient is most commonly a click stimulus, which generates a response from

    Introduction Auditory brainstem implants have become a viable option for patients who suffer from an absent or smaller than normal auditory nerve or an abnormal inner ear, specifically the cochlea. These implants were first designed for patients who were diagnosed with neurofibromatosis type 2, a rare condition that may result in bilateral acoustic neuromas (Johnson 2002). Since then, auditory brainstem implants are now being considered for all patients with nerve or inner ear abnormalities after

    The cochlear implant is a relatively new option in the management of hearing loss. Cochlear implants amplify sound, code sound into an electrical signal, and send those signals into the auditory nerve. The signal then travels to the auditory brainstem and onward to the temporal lobe of the brain for interpretation. The cochlear implant system consists of internal and external components. The internal components include a receiver, an internal magnet, and an electrode array. During a surgical procedure

    digestion, heart rate, pupillary dilation, and urination. However, there are some ANS actions that we are able to control with our mind to a certain extent, such as swallowing. The ANS is positioned just below the medulla oblongata in the lower brainstem. The medulla is responsible for many major functions, such as respiration, cardiac regulation, vasomotor activity, and reflex actions; which include coughing, sneezing, vomiting, and swallowing. The input is received by the hypothalamus, which is

    Introduction Prion disorders, or transmissible spongiform encephalopathies, are a group of diseases that affect the nervous system of humans and animals. Some prion diseases known to date are Creutzfeldt-Jakob Disease and Kuru in humans and Bovine Spongiform Encephalopathy and scrapie in animals (Centers for Disease Control and Prevention, 2012). They are caused by misfolded infectious proteins and known to be transmitted by digesting neural tissue. Prion diseases are very rare and have no known

    In the United States, mistreating a child is extremely looked down upon. Many people reason that children are incapable of caring for themselves, and as such, it is a moral responsibility for adults to care for them. Sadly, this sense of moral obligation does not protect children from being maltreated. Child maltreatment is a term that encapsulates both child abuse and neglect. Child neglect accounts for 49% of all reported cases of maltreatment and is the most common form of child maltreatment (McCoy
