Measurements & Calculations
This is 10% of 35 nasion-inion measurement.
What is 3.5cm?
This EEG system is standard worldwide.
What is the 10-20 system?
EEG tech serve as this between Patient and doctor.
What is a link?
This scientist first recorded electrical brain activity in animals.
Who is Richard Caton?
These electrodes are used to detect eye movement artifact in EEG recording.
What are EOG (eye leads)?
This is 20% of 32cm nasion-inion.
What is 6.4cm?
This system is used for more precise localization.
What is the is the 10-10 system?
This condition is caused by pressure, friction or adhesives.
What is skin breakdown?
This ethical priority ensures no harm comes to the patient.
What is patient safety?
These electrodes are specifically added when temporal lobe epilepsy is suspected
What are anterior temporal electrodes (T1/T2 or sphenoidal electrodes)?
This is the distance between C3 and Cz given 36 cm N-I
What is 6.4 cm?
This electrode position is located on the right temporal region in the 10-20 system
What is T4/T8?
Breach rhythm is seen in this condition.
What is skull defect or post-surgery?
What are ethics?
These electrode provide better coverage of the mesial temporal lobe than standard 10-20 placements.
What are sphenoidal electrodes?
From a 38 cm preauricular measurement, 20% equals this.
What is 7.6 cm?
These electrodes help monitor the mesial temporal lobe.
What are T1, T2, Pg1, Pg2, or sphenoidal electrodes?
EEG techs must follow this principle involving honesty and correctness.
What is accuracy and honesty?
This type of surgery may require intracranial electrode use.
What is tumor resection or brain surgery?
These electrodes are placed inferior to the standard temporal electrodes to increase diagnostic yield
That are T1 and T2?
If the circumference is 60cm, what is 10% of that measurement used in electrode spacing?
This hookup system is used for Visual Evoked Potentials?
What is Queens Square?
This protect patient information.
What is patient confidentiality?
EEG techs must do this with patient data.
What is keep it confidential and secure.
A patient with suspected deep temporal seizure activity would most benefit from adding these electrodes beyond scalp EEG.
What are sphenoidal or intracranial electrodes?
