EEG Pioneers, Descriptors & Definitions

The Shape of You

100

This is the term used to describe the shape of a waveform

Morphology

200

An isolated wave or pattern that is distinctly different from the background is called a what?

Transient 

300

This type of wave has three distinct components usually consisting of a negative-positive-negative look

Triphasic wave

400

A monomorphic EEG pattern can also be described  as this type of wave, resembling sine waves

Sinusoidal

500

This distinct EEG activity is composed of multiple frequencies that combine to form a complex waveform

Polymorphic 

What's the Frequency Kenneth?

100

This type of frequency is not seen in healthy subjects

Dysrhythmic

200

This type of frequency can be described as a constant frequency

Rhythmic

300

This is what frequency is represented in

Hertz or Cycles per second

400

This range of frequency is considered Alpha range

8 to 13 hertz

500

This is the frequency of Theta waves

4 to 7 hertz

Location, Location, Location

100

Abnormal EEG activity that is occurring over all regions of the head is considered to be this

Generalized

200

Abnormal EEG activity occurring from a specific region is often referred to as this

Focal

300

This type of EEG activity only happens on one side of the brain

Lateralized or hemispheric

400

This EEG activity involves three or more brain areas

Multifocal

500

EEG Activity that is occurring on both the right and left hemispheres but not at the same time, is called this

Bilateral or independent bilateral

Pioneers

100

This EEG pioneer was the first person to successfully record spontaneous electrical activity from animal brains by using a rabbit and a monkey

Canton

200

This EEG pioneer was the first to describe Delta and Theta rhythms

Matthews

300

This pioneer was the first to discover what are now called activation procedures used in EEG, by stimulating the cortex of a frog, rabbit and dog

Beck

400

This EEG pioneer was the first to discover somatosensory evoked potentials

Adrian

500

This EEG pioneer is credited as being the "Father of EEG"

Hans Berger

Electro what?

100

This is the instrument or equipment used to record an EEG

Electroencephalograph

200

This is the MD or PhD with expertise who interprets and provides correlation between the EEG and the patient's illness

Electroencephalographer

300

This is the record of the electrical activity of the brain taken by means of electrodes placed on the surface of the scalp

Electroencephalogram

400

This is the science of relating to the electrical activity of the brain.  Also considered the technique of recording EEGs

Electroencephalography

500

This EEG descriptor describes the height or amplitude of a wave. It is represented in microvolts

Voltage
