Electroencephalogram) is a test to detect abnormalities in the brain. The EEG records the brain wave patterns. The most common reason to have an EEG performed is to diagnose and monitor seizure disorders. Other disorder that can be detected is sleep or behavior problems. EEG’s are also used when a brain/ head injury occurs or before surgery like heart or liver transplantation. EEG’s is an interesting test that can save a person life. We will learn a lot about EEG’s in the following paper. Having effective communication is keys to success. Communication is the glue that helps deepen your connections to others and improve teamwork, decision making, and problem solving. Effective communications is a learning skills, it take time to …show more content…
EEG is preform to test the electrical activity in your brain. How we do that is we place 23 electrodes on the patient head. The electrodes are a gold plated disk that is connects to a wire that is connected to a head box. The electrodes are a conductor which has electric current passing through it. The electrodes transfer information form the brain to the wires then to the amplifier to a machine that measures and records the data from the patient brain. EEG can be performed in any healthcare provider office. There are step taken when performing an EEG. At the beginning of the test, EEG technicians will ask the patient or patient caregiver about the patient history, why the EEG is being done, last episode, and when the onset began. Then after all information had been recorded, the patient is asked to lie on their back in a chair or on a bed. Then the technician will begin to mark and measure the patient head with a red pencil. Each mark will be where electrodes will be place on the scalp. After all marking and measuring has been completed, and then we will use a nitty-gritty cream to scrub any oil or dead skin off of the head. It helps the electrodes get a higher quality reading. Now the technician will place 23 electrodes on the patient head with a sticky gel paste on the spots on the scalp. Once the test begins, the electrical impulse date from the brain will be send to a recording machine. This machine will convert that electrical impulse into patterns that will help see if any abnormalities are in the
First, let us look at the electroencephalogram (EEG), which is based on recordings of electrical brain activity with millisecond temporal resolution and it provides “the most direct measure correlate of ongoing brain processing that can be obtained non-invasively (Johnsrude and Hauk, 2010, p. 28). The ba...
Diagnosing Epilepsy can be a long process with lots of steps to follow. When first going thru the process there will need to be a confirmation of parent history. Then there will be a full neurological exam followed by blood and clinical tests, to make sure it wasn’t some other type of episode such as fainting. Apart from the neurological exam, the EEG is the best tool to diagnosing seizures and epilepsy. Then the doctor will identify the type of seizures and do a clinical evaluation to determine the cause of epilepsy. Now depending on the results they will determine the best type of treatment.
In persons suffering from epilepsy, the brain waves, electrical activity in the part of the brain called the cerebral cortex, have a characteristically abnormal rhythm produced by excessive electrical discharges in the nerve cells. Because these wave patterns differ markedly according to their specific source, a recording of the brain waves, known as an electroencephalogram (EEG) is important in the diagnosis and study of the disorder. Diagnosis also requires a thorough medical history describing seizure characteristics and frequency.
In normal sleeping patterns a person usually passes through five phases of sleep, the fifth being REM. The sleeping human passes cyclically through these five phases throughout a night's rest. These phases can be defined in electrical activity of the brain; much like the activity of the heart is often defined. The technique of measuring the electrical activity of the brain is call Electro-encephalogram, or EEG. When the electrical events of a person's brain are graphed on a electrical magnitude versus time axis the graph of a person who is in different stages of being asleep or awake appear to have different levels of electrical activity occurring in the brain. (See (14))
Different maps are taken of the brain in order to determine if there are any problems with the brain. An electroencephalogram (EEG) is used an amplified read out of the brain waves. A magnetic resonance imaging scan (MRI) gives
A seizure is considered to be anything that disrupts the natural circuit of the brain. When a seizure happens, the brains neurons fire uncontrollably, causing the brain to make the body jerk, abruptly fall, or have distorted vision. The normal electrical balance in the brain is lost, the nerve cells misfire, and there is a sudden, brief, uncontrollable burst of abnormal electrical activity. This causes out of sync signals from the brain to misfire (Sahoo, 2014). There are over 3 million people who suffer from epilepsy in the United States alone, with most of them being diagnosed by the time they are twenty-five years old.( Epilepsy Foundation, 2014).
This type of procedure does not reach more than two inches into the brain. The process used is an electromagnetic coil that is held against the clients forehead close to an area of the brain that is considered to be involved in the mood regulation. Next short electromagnetic pulses are administered through the coil. The magnetic pulses pass through the skull, and causes small electrical currents that stimulate nerve cells. The stimulated nerve cells are in
The diagnosis of epilepsy is usually made after the patient experiences a second unprovoked seizure (Leppik, 2002). Diagnosis is often difficult, however, since it is unlikely that the physician will actually see the patient experience and epileptic seizure, and therefore must rely heavily on patient’s history. An electroencephalography (EEG) is often used to examine the patient’s brain waves, and some forms of epilepsy can be revealed by a characteristic disturbance in electrical frequency (Bassick, 1993). The variations in frequency can take form as spikes or sharp waves (Fisher, 1995). The variations are divided into two groups, ictal electrograph abnormalities, which are disturbances resulting from seizure activity, and interictal electrograph abnormalities, or disturbances between seizures. The EEG can also give clues as to which region of the brain the disturbances arise from. Interictal temporal spikes will predict the side of seizure origin in 95% of patients if three times as ...
Another way of psychologists uses to study the brain by studying the electrical activity created by the firing of its neurons. In this method psychologists used one that can be used on living humans, is electroencephalography (EEG). This can be so useful method because an EEG can show if a person is asleep, awake, or
For examining the Brainstem, three important devices that can be used include the EEG, fMRI, and the MEG. Electroencephalography (EEG) Machines are used in laboratories and hospitals. Its purpose is to measure electrical activity generated by cortical layers of the Brain. The electrical signals are from gray matter regions that include many pyramidal cells. Large groups of pyramidal cells generate electricity that soon gets recorded as EEG electrodes. The electrodes go past electric fields and record processes and also monitor different states of the Brain. Examples of states of the Brain are motivation, engagement, and drowsiness. The second machine is the Functional Magnetic Resonance Imaging (FRMI) and it measures brain function by detecting changes in blood flow that relate to neural activity. This is done on the hypothesis that active neurons need a greater amount of oxygen. This device uses a superconducting magnet and it rotates around a person lying down. It measures the magnetization difference in oxygen-rich and oxygen-poor blood, which shows the different levels of brain activity in the different regions. The last machine is the Magnetoencephalography (MEG) Machine which captures magnetic fields that’re generated from neural activity. Just like the FRMI the MEG requires the patient to lay still. It has to happen in a shielded
Brain Computer Interface (BCI) is method to convert brain activities signal to understandable action for machine or robot or any actuator, one of the commonly method to get brain activities is electroencephalography (EEG) system which is easier and low cost and also non-invasive method compare to other brain computer interface systems [1], [2]. In Recent researches of non-invasive brain computer interface based on EEG to control actuators result of create some equipment that controlled with brain, for example electrical wheelchairs [3], mobile Robots [4], humanoid robots [5].
Neuropsychology looks into the brain and what brain damage can be caused by studying the relationship between the brain and the functions. Beaumont (1996) said that neuropsychology is the study of the relationship between the brain and mental life. By bringing ideas from neurology and cognitive psychology it allows analysis of an individual’s abilities and cognitive skills. Neuroimaging has techniques which is able to measure the brain through different scans and images. There are many different techniques used in neuropsychology/neuroimaging that help further our understanding of the brain and how it works, however they all have their faults as well as the positives that they carry. This essay will focus on fMRI, TMS and ECG techniques.
EEG (Electroencephalography) technology is used to measure brain's electrical vibrations from the surface of the scalp. The resulting EEG pattern will contain frequency elements mainly below 30Hz. The frequencies are categorized into four states as follows: State Frequency range Amplitude State of mind
Electroconvulsive therapy was used in the 1900s as a psychiatric treatment when medication would fail to ease patients’ symptoms of clinical depression, suicidal thoughts, or psychiatric illnesses. Using this type of therapy puts the patient at risk for a great amount of side effects when the equipment is misused or under improperly trained staff. The ECT treatment in most cases administered in the morning, or before breakfast. Electroconvulsive therapy has changed, it somewhat still poses risk of side effects. The therapy is more refined today rather than how it was back in the past times.
has concluded that when an EEG reading is what is known as "flat line" the
