EEG facts

100

What does EEG stand for?

Electroencephalography

200

___________ is an imaging technique that measures electrical activity generated by the brain

EEG

300

EEG is was developed in this year

1930s, well actually 1929

400

What the difference between an exogenous component and endogenous component in EEG

Exogenous: External Stimuli

Endogenous: Internal Stimuli

Neurons on the Brain

100

The firing of an individual neuron when the electrical potential of its membrane exceeds its firing threshold

Action potential

200

______ is not optimal in EEG because EEG is measuring a mass of Neurons firing and not a single neuron

Spatial orientation

300

If one neutron is depolarizing and another nearby is re-polarizing, these signals will ______

cancel each other out

400

What are the 5 types of brain frequency bands EEG measures?

delta, theta, alpha (or mu), beta, and gamma

Wow that's Electrifying

100

A solution can be used to enhance electroconductivity between the skin and the electrodes

an electrolyte gel or solution (KCl)

200

An event that the EEG system picks up after a specific stimulus is presented

Event-related potential or time-locked

300

What is the primary source of electrical activity? Hint: Don’t say neuron

post-synaptic potentials

400

In order for EEG to pick up a signal neurons must be oriented _______ and have ________ post-synaptic potentials

parallel, synchronized

Definitions

100

the least amount of electrodes an EEG can use

200

Artifacts can also be generated by changes in skin conductance called

Skin potentials

300

The solution to prevent the amplifier from picking up electrical noise in the environment that could impact active electrode.

differential amplifiers

400

The component that rises as people prepare to make a motor response

lateralized readiness potential (LRP)

Did you do the readings?

When a participant sees a rubber hand being touched and their actual hand is being touched at the same time, they mistakenly think that the rubber hand is their own. This is the experiment is called the

The rubber hand experiment

200

The N140 component was expressed during object and rubber hand group. This suggests that the N140 component relies upon this. (hint timing or object specificity)

on temporal contiguity (timing of the taps)

300

By visually tapping a rubber hand while tapping the person's hidden hand at the same time the researchers aimed to study this.

somatosensory event-related potentials (ERPs)

400

The N140 component is generated by the region of the brain

secondary somatosensory cortex
