EEG & The Brain
What does EEG stand for?
Electroencephalography. Also allowed: Electroencephalogram
The minimum duration for a technically satisfactory Routine EEG recording.
20-minutes
An indention located near the top of the nose
nasion
You can find me 50% of the way between Nasion and Inion
CZ
Unless you have Outpatients scheduled, you are required to be onsite by what time?
What are the 4 lobes of the brain?
frontal, temporal, parietal, occipital lobes
This additional recording method is recommended to accompany EEGs for real-time monitoring of patient behavior?
video recording.
Located on the back of the head, found by sliding your fingers up until you encounter a depression
Inion
These electrodes record electrical activity from the brain's occipital lobe
O1 & O2
In addition to the 10-20 system, what additional leads are required for EEGs at CMC & KWLA?
EKG and A1/A2
EEG recording must be analyzed by what type of medical doctor?
Neurologist
According to ACNS guidelines, how long should HV be performed?
A minimum of 3 minutes, with continued EEG recording for at least 1 minute post HV.
Name all three electrodes that are placed along the midline of the head
Fz, Cz and Pz
How many electrodes complete the International 10-20 system?
19 electrodes (22 if you include electrodes placed on the ear lobes/mastoid and ground)
List all facilities where studies are emailed to the manager, Amber :)
Kindred (Paramount, Westminster & LA), College, and OCM
What are the four frequencies you will encounter when recording EEG? Please list from slowest to fastest.
Delta, Theta, Alpha, and Beta (D-TAB)
Electrodes used in EEG should have an impedance below this value to ensure quality recordings.
5kOhms
What are the 2 different types of montages that are used?
Bipolar and Referential
You will find these electrodes on the left side of the head, recording activity from the frontal lobe
Fp1, F3 & F7
In addition to the 10-20 system, what additional leads are required for EEGs at Fountain Valley Hospital?
Left Eye Electrode and EKG
Please state at least 2 examples that EEG is commonly used for
detection for seizures, epilepsy, stroke, depth of anesthesia
Minimum number of channels required for EEG recording as per ACNS guidelines.
16 channels
What are some types of bipolar montages that are used?
Double Banana & Transverse
Aside to measurement, prepping the skin, and applying the electrodes, what is vital to achieve a quality recording?
symmetry among electrodes
