The Basic Brain

100

contains the visual cortex.

Occipital Lobe

200

contains the motor cortex and conducts higher intellectual functions.

Frontal Lobe

300

connects the two hemispheres of the brain and allows them to "talk" to each other.

Corpus callosum

400

conducts functions for sound, word, and memory patterns. Contains Wernicke's area.

Temporal Lobe

500

A visual representation of the sensory and motor strip. Demonstrates areas that have more sensory or motor pathways. 

Homunculus

The Complex Brain

100

number of ventricles inside the brain that help circulate cerebrospinal fluid. 

four (4)

200

acts as a "cushion" for the brain and spinal cord and circulates in the space between the skull and brain. A buildup of this can lead to hydrocephalus. 

Cerebrospinal fluid

300

sits below the occipital lobe. Regulates and coordinates fine motor functions. Is often referred to as the "little brain".

Cerebellum

400

Controls basic life sustaining functions (keeps heart beating, respiratory drive, etc.) and is made of 3 smaller parts. 

Brainstem

500

3 parts that make up the brain stem. 

midbrain, pons, medulla oblongata

Electrodes and Placement

100

If the distance from f7 to f8 is 22cm, what is the distance from fz to f4?

5.5cm

200

if the distance from the inion to Oz is 3.5cm, what is the distance from Fz to Pz?

14cm

300

Can be as another name for A1/2. Is named for the muscle that these electrodes sit over. 

M1/2 (M = mastoid)

400

these electrodes are often used as additional electrodes when monitoring a patient with known temporal lobe epilepsy.

T1/2 or FT9/10

500

These are additional electrodes can be added to a montage. They are often added to patients with seizures coming from the motor/sensory strip area. They can be found between T3/4 to C3/4 and C3/4 to Cz. (4)

C1/2 and C5/6

Random EEG Knowledge

100

The age when sleep spindles should become synchronous and symmetrical. 

2 years

200

variant found over the C3/4 electrodes with a frequency of 7-11Hz. Is often called the "PDR of the motor strip" and named for its "cat-like appearance"

Mu

300

This seizure disorder is associated with multiple different seizure types and intellectual disability. 

Lennox Gastau Syndrome (LGS)

400

This seizure disorder is associated with sleep activated discharges seen in the centro-temporal areas. It's seen in children who often out-grow this syndrome. It's name has been changed multiple times over the years. 

Rolandic epilepsy, BECTS, SLECTS

500

This EEG feature is not associated with seizures, but is found in children that experience sudden academic decline or difficulty.

Continuous Spike Wave in Sleep (CSWS)
