Transcript: During - Electrodes are placed on the patient's scalp to detect electrical impulses within the brain - Normal findings are normal frequency, amplitude and characteristics of brain waves - Abnormal findings: seizures, brain tumor, brain abscess, intracranial hemorrhage, cerebral infarct, cerebral death, encephalitis, narcolepsy (detects sleep waves during normal waking hours), metabolic encephalopathy Overview Teaching Electroencephalography Highlights After - Instruct the patient to wash his hair the night before the test. Patient should not use any oils or sprays - Instruct patient not to drink any coffee, tea, cocoa, or cola the morning before the test - Instruct patient he will need to remain still during the test - Instruct the patient that he should not fast before the test. (Pt should eat to avoid hypoglycemia) *to identify brain function abnormalities * Due to the EEG's ability to evaluate the overall electrical activity of the brain, it can be used to determine trauma and cerebral death - Help the patient to remove the electrode paste with acetone - Instruct and help patient shampoo hair - Instruct patient who has had a sleep EEG not to drive home alone - Ensure safety precautions until the effects of any sedatives have worn off if sleep EEG indicated Before Complications/contraindication/ interfering factors * to identify and evaluate patients with seizures *identify conditions involving the brain cortex *tumors *infarction *abscess - Procedure performed by an EEG technician so nurse is generally not present for procedure - Help the patient to lie in a supine position - Patient is asked to hyperventilate by breathing deeply 20 times per minute for 3 minutes - Light may be flashed over the patient with the patient's eyes opened or closed - Electrodes will cover prefrontal, frontal, temporal, parietal, occipital areas of the skull - Patient may be asked to hyperventilate by breathing deeply 20 times per minute for 3 minutes - Light may be flashed over the patient with the patient's eyes closed or opened (to detect light-stimulated seizures) Procedure and Findings Purpose - Explain procedure to patient - Assure patient that the test cannot read minds or test senility - Assure patient that he will not feel anything during the procedure - Instruct the patient to wash his hair the night before the test. Patient should not use any oils or sprays - Check with physician if any medications need to be discontinued - Instruct patient if sleeping time should be shortened the night before the test - Instruct patient not to fast before study - Instruct patient not to drink any coffee, tea, cocoa, or cola the morning before the test - Instruct patient he will need to remain still during the test - Fasting causing hypoglycemia - Drinks containing caffeine - Movement during the test - Light can alter results - Drugs such as sedatives - Seizure can be induced due to the hyperventilation and flashing lights - EEG is primarily used for identifying epilepsy, but can also identify cerebral death as well as be used in a craniotomy - Be sure to instruct the patient to wash his hair the night before and not to use oils or lotions - Be sure to instruct the patient to eat before the test to avoid hypoglycemic reaction -Be sure to instruct patient to avoid caffeinated beverages EEG

Transcript: A new product called Eeg™, short for Eeg Superegg Solution™, just hit the market, changing the game forever. Nothing will ever be the same in this world. Unregulated, objectively experimental, the places this product can reach are limitless. The creator, Ben Bayer, remarks than even he does not know the full potential Eeg™ possesses. Enhanced dexterity, super speed, computational powers beyond anything you've ever dreamed, you can have it all. You cannot, and will not, be prepared for what it will do to you. John Nownes: Greatest Athlete of All Time Creighton Prep's very own John Nownes, greatest athlete ever to be born on this earth, has said in a recent interview that it was only possible because of Eeg™. "It changed my life forever," he said while on his daily marathon. "I never could have been here if it wasn't for Eeg™, it made my every dream come true." "Eeg™ is everything to me" -Jude Peal "Eeg™ won me the lottery!" -Tom Ernatt "Without Eeg™, I would've had no chance of getting through finals" -every single Creighton Prep student Ben Bayer, creator of Eeg Superegg Solution™, has remained predominately silent these past few days despite now being possibly the most successful, influential, and powerful man in the world. Here at CP Daily News we are still trying to get an interview, but until later notice we do not have confirmation. Some say he's undoubtedly retreated to a remote cave in rural Tibet, yet others say with certainty he is hiding out at a college preparatory school. So for now, keep your eyes open, and God bless America. How is he so godly? Story by Liam Keating, voice of Operation Others $2.50 Saturday, December 10, 2016 What Does The Creator Have To Say? Trump Reveals His Secret CUSTOMERS RAVE! Buy Eeg™ Now! EEG CHANGES THE MARKET FOREVER Eeg: The Future How did he really get elected? Despite the news, little said so far Now that Trump has secured the presidency, he is finally revealing how he really got there. The answer? Eeg™. But not just any Eeg™, he had his own personalized presidential Eeg™. Vol XCIII, No. 217 CP DAILY NEWS Hear their real stories

EEG measures voltage fluctuations resulting from ionic current flows within the neurons of the brain. EEG activity therefore always reflects the summation of the synchronous activity of thousands or millions of neurons. EEG signals are commonly used for diagnosis of brain disorders such as Alzheimer’s and epilepsy. The activity of each brain area of the brain is represented by a different tree, where trees grow and bloom, and birds whistle. The forest is less active: the trees are less developed, there are hardly any red flowers, and there are few birds sound. Brain waves measured by a wireless headset Alzheimer's Patients The aim of this study is to provide an alternative tool for analyzing and exploring brain signals (specifically for Alzheimer's disease) through novel graphical and auditory representations. What is EEG ? Four brain areas will be mapped into four trees
