• 1 EEG

• 1.1 History

• Who was Berger H. And what did he work on?

  - German scientist, worked on EEG in his free time
  - tried capturing brain potential from scalp

• What did Berger H publish in 1929?

  His first results on alpha-waves from the brain of his son

• Who was the first person recording EEG in 1912?

  Russian scientist Pradvdich Neminski

• 1.2 EEG signals

• The brain consists of white and grey matter, the cortex consists of 6 layers. Which 2 are the most relevant for EEG?

  - layer 1 and 5
  - pyramidalis interna neurons with dendrites point all the way upwards from layer 5 to 1

• How are pyramidal interns neurons organized?

  In orderly vertical fashion

• Input measured with EEG comes from:

  Layer 5 
  - only layer 5 and 1 can be measured from the scalp

• Why is it difficult to find out the input of just one neuron?

  Because EPSP and IPSP is a continuous effort, from 1000s of input at the same time

• What does spontaneous EEG mean?

  Is a mix of all frequency's bands

• Explain the study about resting state activity and gambling behavior.

  - used low gambling task in which low risk behavior will eventually make people earn more
  - depending on asymmetry of the PFC in the left side of brain --> more reward driven and take more risks

• Explain the study where they used symmetrical frontal cortical activity to measure aggression.

  - participants had to write essays about different political topic (like abortion)
  - after they all got EEG + envelope
  - some instructed to do nothing, others to contract their right hand, last group their left hand
  - after EEG manipulation + contracting: social setup where participant and insulter played in punishing task
  --> Found: people who were in assaulted condition + hand to squeeze right hand punished the insulter the most
  => squeezing right hand --> increased activity on left side of brain in frontal area --> most pronounced anger
