Electroencephalography (EEG) Technology Applications and Available Devices
applied sciences Review Electroencephalography (EEG) Technology Applications and Available Devices Mahsa Soufineyestani , Dale Dowling and Arshia Khan * Department of Computer Science, University of Minnesota Duluth, Duluth, MN 55812, USA; soufi[email protected] (M.S.); [email protected] (D.D.) * Correspondence: [email protected] Received: 18 September 2020; Accepted: 21 October 2020; Published: 23 October 2020 Abstract: The electroencephalography (EEG) sensor has become a prominent sensor in the study of brain activity. Its applications extend from research studies to medical applications. This review paper explores various types of EEG sensors and their applications. This paper is for an audience that comprises engineers, scientists and clinicians who are interested in learning more about the EEG sensors, the various types, their applications and which EEG sensor would suit a specific task. The paper also lists the details of each of the sensors currently available in the market, their technical specs, battery life, and where they have been used and what their limitations are. Keywords: EEG; EEG headset; EEG Cap 1. Introduction An electroencephalography (EEG) sensor is an electronic device that can measure electrical signals of the brain. EEG sensors typically measure the varying electrical signals created by the activity of large groups of neurons near the surface of the brain over a period of time. They work by measuring the small fluctuations in electrical current between the skin and the sensor electrode, amplifying the electrical current, and performing any filtering, such as bandpass filtering [1]. Innovations in the field of medicine began in the early 1900s, prior to which there was little innovation due to the uncollaborative nature of the field of medicine. -
10 Dangerous Drugs That Attack Your Brain and Body (PDF)
ALCOHOL Legal but dangerous. Causes changes in behavior, impairs judgement and coordination required to drive a car safely. Moderate to high doses severely alters a person's ability to learn and remember. Very high doses cause death. 10 Dangerous Drugs: Long term consumption of large quantities, combined with poor nutrition, can lead to permanent damage to brain. liver, pancreas and stomach. That attack your Brain and AMPHETAMINES Body Illegal. Users may experience sweating, headaches, blurred vision, dizziness, sleeplessness and anxiety. High doses can cause irregular heartbeat, loss of coordination, and collapse. Injection creates a sudden increase in blood pressure that can result in very high fever, or heart failure and death. BARBITURATES Illegal. Effects are similar of those of alcohol: slurred speech, staggering walk. Very large doses can cause coma and death. Combination of barbiturates and alcohol multiplies risks. COCAINE Illegal. Stimulates the central nervous system. Immediate effects include dilated pupils, elevated blood pressure, heart and respiratory problems, and stuffy nose. Crack, or freebase rock, is extremely addictive, and effects are felt within 10 seconds! Causes dilated pupils, increased pulse rate, elevated blood pressure, insomnia, loss of appetite, hallucinations, paranoia, and seizures. Use of cocaine can cause death by cardiac arrest. HALLUCINOGENS Lysergic acid. (LSD) Commonly causes sensations and feelings to change rapidly. Causes illusions (being deceived by the normal) and hallucinations (a false or mistaken idea) dilated pupils, elevated body temperature, increased heart rate and blood pressure, loss of appetite, sleeplessness and tremors. The user may experience panic, confusion, suspicions, anxiety and loss of control. Delayed effects (flashbacks), can occur even after use has ceased. -

Tumor Treatment Fields Therapy When It Is Determined to Be Medically Necessary Because the Medical Criteria Shown Below Are Met
Corporate Medical Policy Tumor-Treatment Fields Therapy File Name: tumor_treatment_fields_therapy Origination: 9/2013 Last CAP Review: 8/2021 Next CAP Review: 8/2022 Last Review: 8/2021 Description of Procedure or Service Tumor-treatment fields therapy is a noninvasive technology that uses alternating electrical fields. It is used to treat glioblastoma multiforme and has been proposed for use in other tumor types. Glioblastoma, also known as glioblastoma multiforme (GBM), is the most common form of malignant primary brain tumor in adults, comprising approximately 38% of all brain and central nervous system tumors. The peak incidence for GBM occurs between the ages of 45 and 70 years, with a median age at diagnosis of 64 years. GBMs are grade IV astrocytomas, a rapidly progressing and deadly type of glial cell tumor, which is often resistant to standard chemotherapy. According to the National Comprehensive Cancer Network (NCCN), GBM is the "deadliest brain tumor with only a third of patients surviving for one year and less than 5% living beyond 5 years." Treatment of Newly Diagnosed Glioblastoma Multiforme The primary treatment for newly diagnosed GBM is to resect the tumor to confirm a diagnosis while debulking the tumor to relieve symptoms of increased intracranial pressure or compression. If total resection is not feasible, subtotal resection and open biopsy are options. During surgery, some patients may undergo implantation of the tumor cavity with a carmustine (BCNU) - impregnated wafer. Due to the poor efficacy of local treatment, postsurgical treatment with adjuvant radiotherapy, chemotherapy (typically temozolomide), or a combination of these 2 therapies is recommended. After adjuvant therapy, some patients may undergo maintenance therapy with temozolomide. -
Intersectional Approaches to African American Addiction Dissertation
Recovering Women: Intersectional Approaches to African American Addiction Dissertation Presented in Partial Fulfillment of the Requirements for the degree Doctor of Philosophy in the Graduate School of The Ohio State University By Tracy Carpenter, M.A. Graduate Program in Comparative Studies The Ohio State University 2009 Dissertation Committee: Amy Shuman, Advisor Nina Berman Valerie Lee Maurice Stevens Copyright by Tracy Carpenter 2009 ABSTRACT This dissertation uses an interdisciplinary approach to examine the sociopolitical impact and ideological work of stereotypes that stigmatize people with intersecting identities. Focusing on the Crack Mother icon, I first examine how misrepresentations in films, media and literature influence legislation and policies that target poor women of color for punishment. I contextualize the Crack Mother as part of a continuum of cultural icons that represent African American women as deviant. I then incorporate data from ethnographic research among African American Narcotics Anonymous groups to offer an alternative version of African American women’s experience with drug addiction and use of twelve-step recovery approaches. Positing self-representation at the forefront prioritizes perspectives that challenge dominant narratives of addiction. The presentation of African American women as conscientious participants within a folk culture that values determined living turns on its head Western notions of expertise, organization, temporality, illness and so forth. The project is grounded in cultural studies, folklore, and African and African American studies. I incorporate critical race theory when conducting discourse analysis with films and literature from popular culture. I use alignment theory to flesh out participants’ footing in racial, social, gender, religious and other identities using data gathered from ethnographic interviews with 10 African American women members of twelve-step programs with two and more years of continuous abstinence. -

Although some of the problems brain tumor patients experience at the end of life are common with many other forms of cancer, there is a subset of challenging problems unique to patients with brain tumors. In fact, the end-of-life phase for brain tumor patients tends to have a different course than general cancer patients. The intent of this manual is to suggest recommendations regarding disease-specific symptoms. Over time, recommendations will likely change as new supportive treatments are incorporated into clinical care. We understand that each patient’s situation is unique and that the end of life is different for each patient. -

Phantoms in the Brain.Pdf
PHANTOMS IN THE BRAIN Probing the Mysteries of the Human Mind V.S. Ramachandran, M.D., Ph.D., and Sandra Blakeslee Copyright © 1998 ISBN 0688152473 To my mother, Meenakshi To my father, Subramanian To my brother, Ravi To Diane, Mani and Jayakrishna To all my former teachers in India and England 1 To Saraswathy, the goddess of learning, music and wisdom Foreword The great neurologists and psychiatrists of the nineteenth and early twentieth centuries were masters of description, and some of their case histories provided an almost novelistic richness of detail. Silas Weir Mitchell—who was a novelist as well as a neurologist—provided unforgettable descriptions of the phantom limbs (or "sensory ghosts," as he first called them) in soldiers who had been injured on the battlefields of the Civil War. Joseph Babinski, the great French neurologist, described an even more extraordinary syndrome—anosognosia, the inability to perceive that one side of one's own body is paralyzed and the often−bizarre attribution of the paralyzed side to another person. (Such a patient might say of his or her own left side, "It's my brother's" or "It's yours.") Dr. V.S. Ramachandran, one of the most interesting neuroscientists of our time, has done seminal work on the nature and treatment of phantom limbs—those obdurate and sometimes tormenting ghosts of arms and legs lost years or decades before but not forgotten by the brain. A phantom may at first feel like a normal limb, a part of the normal body image; but, cut off from normal sensation or action, it may assume a pathological character, becoming intrusive, "paralyzed," deformed, or excruciatingly painful—phantom fingers may dig into a phantom palm with an unspeakable, unstoppable intensity. -

Medicine in Alexandre Dumas Père's the Count of Monte Cristo
Belphégor Jock Murray Medicine in Alexandre Dumas père's The Count of Monte Cristo Alexandre Dumas was one of the most prolific writers of all time. First a successful playwright, he later expanded into every aspect of profitable writing which would include hundreds of historical and romantic novels, essays, plays, travel books, cook books, and hundreds of newspaper stories and articles. His books number over 600, but no one is sure exactly how many and André Maurois said no one has read all of Dumas, a feat as impossible as the writing would seem to be. Dumas wrote 4- 6 novels at a time, publishing a shelf of books each year. During the period 1841 to 1850, nine years, he published 41 novels, 23 plays, 7 historical works, and 6 travel books, all of them successful. A recently found novel of Dumas (La Maison de Savoie) is 2500 pages long, which is understandable as he serialized his novels in newspapers, continuing the story day after day, and he was paid by the line. The Count of Monte Cristo is Alexandre Dumas' idealized personal fantasy, one which is a central one in fable and literature. Perhaps it has occurred to every child who believes they are unjustly treated, blamed or bullied, that they might return in a form unrecognizable to enemies, with great power, wealth, secret knowledge and skills with which they can take revenge in clever and devious ways, righting the grievous wrongs. It may be a childish dream ideal but it lingers in the hearts of adults. The Count of Monte Cristo, a roman de moeurs, became one of the most popular novels in the world.
