EEG pros correct answer: Excellent time resolution - Cognitive, perceptual, linguistic, emotional processes are fast and dynamic - For example, consider theta band (4-8 Hz), a slow rhythm but quite fast for our conscious experience - Or consider gamma (30 -80 Hz) Direct indicator of neuronal activity Multidimensional (time, space, frequency, power, phase, connectivity etc) Portability (observing brain in action) Relatively inexpensive EEG cons correct answer: It is not well-s...

Electroencephalogram (EEG) Test correct answer: Electrodes are applied to the scalp, and the electrical activity of the brain is monitored. EEG is used to detect seizure activity and disorders. test used to find problems related to ELECTRICAL ACTIVITY of the BRAIN. A client is scheduled for an EEG after having a seizure for the first time. Client preparation for this test should include which instruction? correct answer: "Avoid stimulants and alcohol for 24 to 48 hours before the test ...

Chapter 85: Drugs That Weaken the Bacterial Cell Wall II: Cephalosporins, Carbapenems, Vancomycin, Telavancin, Aztreonam, Teicoplanin, and Fosfomycin. MULTIPLE CHOICE 1. A patient who is receiving a final dose of intravenous (IV) cephalosporin begins to complain of pain and irritation at the infusion site. The nurse observes signs of redness at the IV insertion site and along the vein. What is the nurse’s priority action? a. Apply warm packs to the arm, and infuse the medication at a slo...

What is Electroencephalography (EEG)? correct answer: A method of detecting neural activity by placing electrodes on the scalp How does EEG work? correct answer: Electrodes pick up small fluctuations of electrical signals, originating from activity of (mostly cortical) neurons Nature of electrical signals correct answer: Very noisy and might not look like much but systematically related to cognitive processes How is EEG recorded? correct answer: Either at the scalp (non-invasive) bu...

Electroencephalography (EEG) Questions and Answers 100% Accurate What is an EEG (electroencephalograph)? Electroencephalography (EEG) is a method of detecting neural activity by placing electrodes on the scalp. EEG recorded at the scalp is non-invasive - however, it is also possible to record intra-cranial EEG by measuring activity directly at the exposed cortex. EEG is cheap and (relatively) easy to conduct. The temporal resolution of an EEG is great, but the spatial resolution is poor. ...

An imaging technique that reads scalp electrical activity correct answer: EEG EEG measures mostly... correct answer: the currents that flow during synaptic excitations of the dendrites of many pyramidal neurons in the cerebral cortex Only large populations of active neurons can generate... correct answer: electrical activity recordable on the head surface The highest influence to the EEG comes from the... correct answer: elecrtical activity of the cerebral cortex due to its surface ...
