1

What does ERP stand for?

Event-Related Potential

2

Who studied the electrical properties of the nervous system and found evidence for fine localization of function in the cortex (by stimulating dogs--> involuntary movement)

Gustav Fristch & Eduard Hitzig

3

What is David Ferrier known for?

He stimulated dogs and monkeys and located precise areas for motor control

4

What is Richard Caton known for?

He measured precise activity of the brain (without stimulation) in dogs--birth of EEG (1875)

5

Who first reported alpha supression?

Adolf Beck

6

Who built the first EEG?

Hans Berger (first EEG recording in man on his own son, Klaus; also first to distinguish alpha & beta waves)

7

Who first distinguished alpha & beta waves?

Hans Berger

8

Who is considered to be the "father of electroencephalography"?

Hans Berger

9

Who pioneered the use of EEG as a diagnostic tool (reported abnormal EEG in epilepsy)?

Frederic Gibbs

10

Who reported the first cognitive component (CNV)?

Grey Walter (Contingent Negative Variation, 1964) - inspired research of ERPs

11

Who discovered the P3 component in 1965?

Samuel Sutton

12

Which frequency band ranges from 30-80Hz?

Gamma

13

Which frequency band ranges from 14-30Hz?

Beta

14

Which frequency band ranges from 8-13Hz?

Alpha

15

Which frequency band ranges from 4-7Hz?

Theta

16

Which frequency band ranges from 1-4Hz?

Delta

17

What does EEG reflect?

Dendritic activity of synchronized neocortical pyramidal cells

18

What do ERPs reflect?

Brain activity relative to a given point in time (stimulus or response)

19

Where does the PCN wave (N2PC) originate from?

The ventral occipito-temporal cortex

20

What is the PCN wave hypothesized to reflect?

Attentional selection, or suppression of interference from distractors

21

Where does the LRP wave originate from?

Motor areas (strongest over areas contralateral to a hand/foot movement)

22

What is the LRP wave believed to reflect?

Preparation or activation of a motor response

23

Who did the first EEG recording in man?

Hans Berger (1929)

24

What was the first cognitive ERP component?

Contingent Negative Variation (CNV) - Grey Walter, 1964

25

What are the few advantages of ERP over fMRI and PET?

Excellent temporal resolution (but poor spatial), inexpensive, portable/mobile

26

Order the 5 frequency bands in order from lowest Hz to highest Hz.

Delta (1-4), Theta (4-7), Alpha (8-13), Beta (14-30), Gamma (30-80)
