Lecture 3 & 4: Electroencephalography
(EEG) Exam Questions and Answers
100% Pass
What is Electroencephalography (EEG)? - ✔✔A method of detecting neural activity by placing electrodes
on the scalp
How does EEG work? - ✔✔Electrodes pick up small fluctuations of electrical signals, originating from
activity of (mostly cortical) neurons
Nature of electrical signals - ✔✔Very noisy and might not look like much but systematically related to
cognitive processes
How is EEG recorded? - ✔✔Either at the scalp (non-invasive) but also possible to record
intra-cranial EEG by measuring activity directly at the exposed cortex
Logistics of EEG - ✔✔Cheap and (relatively) easy to conduct
Hans Berger (1873-1941) - ✔✔Detected the first EEG signal in 1924 with electrodes attached to the scalp of
a human (his wife) and reported the results in 1929
Why did Burger study medicine? - ✔✔Because he was convinced that there is "psychic energy", which
might allow for telepathy

He wanted to discover the objective activity in the brain and "psychic phenomena", but he did not realise
the basis and potential of his discovery at the time
What else did Burger describe? - ✔✔Alpha rhythm: characteristic frequency of electrical signal when eyes
closed
What is the characteristic frequency of alpha rhythm? - ✔✔8-13 Hz
How did Burger measure electrical activity? - ✔✔Initially, he used two electrodes, one attached to the
front of the head and one to the rear, and recorded the potential (i.e. voltage) difference between them.
Initially, electrodes were silver wires placed under the scalp
Later, sliver foil placed on the scalp
Advantage of EEG - ✔✔Great temporal resolution
Disadvantage of EEG - ✔✔Poor spatial resolution
In the electrode cap, on which side are odd numbers? - ✔✔Left side
In the electrode cap, on which side are even numbers? - ✔✔Right side
What does EEG activity reflect? - ✔✔The EEG activity does not reflect action potentials but originates
mostly from post-synaptic potentials - voltages that arise when neurotransmitters bind to receptors on the
membrane of the post-synaptic cell
This causes ion channels to open or close, leading to graded changes in the potential across the membrane
